and associated runtest file fs_ext4.

The main reason is that these tests [1] (contributed in 2009)
are mostly outdated and irrelevant. According to Theodore Y. Tso [2]
and Jan Kara [3] the only partly valid tests are
ext4_nsec_timestamps_test.sh and ext4_subdir_limit_test.sh,
but even these would be better to migrate to xfstests,
which Yong Sun is planning to do.

Also, some of the tests weren't in any runtest file anyway
(ext4-alloc-test.sh, ext4_inode_version_test.sh,
ext4_journal_checksum.sh, ext4_online_defrag_test.sh)

ffsb tool was used only in these New ext4 features tests.

Acked.

The ffsb adds quite a bit of complexity to the LTP build with a very
little added value. As far as the meaningful parts of the ext4 suite
would be migrated to xfstests everyone should be happy about this.

-TEST SUITE:
-
-The directory ext4-new-features contains the tests related to the ext4
-filesystem's new features.
-
-Ext4 is an advanced level of the ext3 filesystem which incorporates scalability
-and reliability enhancements for supporting large filesystems(64 bit) in keeping
-with increasing disk capacities and state-of-the-art feature requirements. More
-extensive information of ext4 can be found at the ext4 wiki site at the URL:
-http://ext4.wiki.kernel.org
-
-There are total 117 testcases for ext4 new features test that have been added.
-Now, these testcases can test multi-block alloc/delayed alloc, inode version
-field on disk, journal checksumming, nanosec timestamps, online defrag, persist
-prealloc, subdirectory limit and uninit groups of ext4.
-The detail information of ext4 new features can be found at the URL:
-http://ext4.wiki.kernel.org/index.php/New_ext4_features
-
-
-TESTS AIM:
-
-The aim of the tests is to test ext4 new features.
-
-
-TEST STEPS:
-# cd LTPROOT/testcases/kernel/fs/ext4-new-features
-# make
-# make install
-# cd LTPROOT
-# ./runltp -f fs_ext4 -z 'big unmounted block device partition'
-
-
-NOTE:
-
-1. This test can be run by root only.
-
-2. These tests need a big unmounted block device partition. You MUST run runltp
-   with "-z" option to specify such a big block device, if not, these tests
-   will exit with TCONF.
-
-   Be CAREFUL the data on the specified partition would be DESTROYED.
-
-   The recommended size of partition is between 5G and 10G. If the partition is
-   too big, the test will run for a long time, which is unnecessary.
-
-3. Before starting test ext4 new features, please check whether ext4 filesystem
-   is compiled into the kernel or not, and the kernel version is *2.6.31* or
-   above.
-
-4. A snapshot of config file options is given below:
-   ONFIG_EXT4_FS=y
-   CONFIG_EXT4DEV_COMPAT=y
-   CONFIG_EXT4_FS_XATTR=y
-   CONFIG_EXT4_FS_POSIX_ACL=y
-   CONFIG_EXT4_FS_SECURITY=y
-
-5. Beside that, the following packages are necessary:
-   e2fsprogs
-     (http://www.rpmfind.net/linux/rpm2html/search.php?query=e2fsprogs)
-   e2fsprogs-devel
-     (http://www.rpmfind.net/linux/rpm2html/search.php?query=e2fsprogs-devel)
-   e2fsprogs-libs
-     (http://www.rpmfind.net/linux/rpm2html/search.php?query=e2fsprogs-libs)
-   and the version of these packages should be 1.41.4 or above, otherwise the
-   test will fail.
-

-		    GNU GENERAL PUBLIC LICENSE
-		       Version 2, June 1991
-
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.
-     59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-			    Preamble
-
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users.  This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it.  (Some other Free Software Foundation software is covered by
-the GNU Library General Public License instead.)  You can apply it to
-your programs, too.
-
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
-  To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
-  For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have.  You must make sure that they, too, receive or can get the
-source code.  And you must show them these terms so they know their
-rights.
-
-  We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
-  Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software.  If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
-  Finally, any free program is threatened constantly by software
-patents.  We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary.  To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-		    GNU GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-  0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License.  The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language.  (Hereinafter, translation is included without limitation in
-the term "modification".)  Each licensee is addressed as "you".
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
-  1. You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
-  2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-    a) You must cause the modified files to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    b) You must cause any work that you distribute or publish, that in
-    whole or in part contains or is derived from the Program or any
-    part thereof, to be licensed as a whole at no charge to all third
-    parties under the terms of this License.
-
-    c) If the modified program normally reads commands interactively
-    when run, you must cause it, when started running for such
-    interactive use in the most ordinary way, to print or display an
-    announcement including an appropriate copyright notice and a
-    notice that there is no warranty (or else, saying that you provide
-    a warranty) and that users may redistribute the program under
-    these conditions, and telling the user how to view a copy of this
-    License.  (Exception: if the Program itself is interactive but
-    does not normally print such an announcement, your work based on
-    the Program is not required to print an announcement.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
-    a) Accompany it with the complete corresponding machine-readable
-    source code, which must be distributed under the terms of Sections
-    1 and 2 above on a medium customarily used for software interchange; or,
-
-    b) Accompany it with a written offer, valid for at least three
-    years, to give any third party, for a charge no more than your
-    cost of physically performing source distribution, a complete
-    machine-readable copy of the corresponding source code, to be
-    distributed under the terms of Sections 1 and 2 above on a medium
-    customarily used for software interchange; or,
-
-    c) Accompany it with the information you received as to the offer
-    to distribute corresponding source code.  (This alternative is
-    allowed only for noncommercial distribution and only if you
-    received the program in object code or executable form with such
-    an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it.  For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable.  However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License.  Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
-  5. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Program or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
-  6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
-  7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded.  In such case, this License incorporates
-the limitation as if written in the body of this License.
-
-  9. The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time.  Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number.  If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation.  If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
-  10. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission.  For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this.  Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
-			    NO WARRANTY
-
-  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
-  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
-POSSIBILITY OF SUCH DAMAGES.
-
-		     END OF TERMS AND CONDITIONS
-
-	    How to Apply These Terms to Your New Programs
-
-  If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
-  To do so, attach the following notices to the program.  It is safest
-to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the program's name and a brief idea of what it does.>
-    Copyright (C) <year>  <name of author>
-
-    This program is free software; you can redistribute it and/or modify
-    it under the terms of the GNU General Public License as published by
-    the Free Software Foundation; either version 2 of the License, or
-    (at your option) any later version.
-
-    This program is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
-    GNU General Public License for more details.
-
-    You should have received a copy of the GNU General Public License
-    along with this program; if not, write to the Free Software
-    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
-
-
-Also add information on how to contact you by electronic and paper mail.
-
-If the program is interactive, make it output a short notice like this
-when it starts in an interactive mode:
-
-    Gnomovision version 69, Copyright (C) year  name of author
-    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
-    This is free software, and you are welcome to redistribute it
-    under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License.  Of course, the commands you use may
-be called something other than `show w' and `show c'; they could even be
-mouse-clicks or menu items--whatever suits your program.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the program, if
-necessary.  Here is a sample; alter the names:
-
-  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
-  `Gnomovision' (which makes passes at compilers) written by James Hacker.
-
-  <signature of Ty Coon>, 1 April 1989
-  Ty Coon, President of Vice
-
-This General Public License does not permit incorporating your program into
-proprietary programs.  If your program is a subroutine library, you may
-consider it more useful to permit linking proprietary applications with the
-library.  If this is what you want to do, use the GNU Library General
-Public License instead of this License.

-Basic Installation
-==================
-
-   These are generic installation instructions.
-
-   The `configure' shell script attempts to guess correct values for
-various system-dependent variables used during compilation.  It uses
-those values to create a `Makefile' in each directory of the package.
-It may also create one or more `.h' files containing system-dependent
-definitions.  Finally, it creates a shell script `config.status' that
-you can run in the future to recreate the current configuration, a file
-`config.cache' that saves the results of its tests to speed up
-reconfiguring, and a file `config.log' containing compiler output
-(useful mainly for debugging `configure').
-
-   If you need to do unusual things to compile the package, please try
-to figure out how `configure' could check whether to do them, and mail
-diffs or instructions to the address given in the `README' so they can
-be considered for the next release.  If at some point `config.cache'
-contains results you don't want to keep, you may remove or edit it.
-
-   The file `configure.in' is used to create `configure' by a program
-called `autoconf'.  You only need `configure.in' if you want to change
-it or regenerate `configure' using a newer version of `autoconf'.
-
-The simplest way to compile this package is:
-
-  1. `cd' to the directory containing the package's source code and type
-     `./configure' to configure the package for your system.  If you're
-     using `csh' on an old version of System V, you might need to type
-     `sh ./configure' instead to prevent `csh' from trying to execute
-     `configure' itself.
-
-     Running `configure' takes awhile.  While running, it prints some
-     messages telling which features it is checking for.
-
-  2. Type `make' to compile the package.
-
-  3. Optionally, type `make check' to run any self-tests that come with
-     the package.
-
-  4. Type `make install' to install the programs and any data files and
-     documentation.
-
-  5. You can remove the program binaries and object files from the
-     source code directory by typing `make clean'.  To also remove the
-     files that `configure' created (so you can compile the package for
-     a different kind of computer), type `make distclean'.  There is
-     also a `make maintainer-clean' target, but that is intended mainly
-     for the package's developers.  If you use it, you may have to get
-     all sorts of other programs in order to regenerate files that came
-     with the distribution.
-
-Compilers and Options
-=====================
-
-   Some systems require unusual options for compilation or linking that
-the `configure' script does not know about.  You can give `configure'
-initial values for variables by setting them in the environment.  Using
-a Bourne-compatible shell, you can do that on the command line like
-this:
-     CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
-
-Or on systems that have the `env' program, you can do it like this:
-     env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
-
-Compiling For Multiple Architectures
-====================================
-
-   You can compile the package for more than one kind of computer at the
-same time, by placing the object files for each architecture in their
-own directory.  To do this, you must use a version of `make' that
-supports the `VPATH' variable, such as GNU `make'.  `cd' to the
-directory where you want the object files and executables to go and run
-the `configure' script.  `configure' automatically checks for the
-source code in the directory that `configure' is in and in `..'.
-
-   If you have to use a `make' that does not supports the `VPATH'
-variable, you have to compile the package for one architecture at a time
-in the source code directory.  After you have installed the package for
-one architecture, use `make distclean' before reconfiguring for another
-architecture.
-
-Installation Names
-==================
-
-   By default, `make install' will install the package's files in
-`/usr/local/bin', `/usr/local/man', etc.  You can specify an
-installation prefix other than `/usr/local' by giving `configure' the
-option `--prefix=PATH'.
-
-   You can specify separate installation prefixes for
-architecture-specific files and architecture-independent files.  If you
-give `configure' the option `--exec-prefix=PATH', the package will use
-PATH as the prefix for installing programs and libraries.
-Documentation and other data files will still use the regular prefix.
-
-   In addition, if you use an unusual directory layout you can give
-options like `--bindir=PATH' to specify different values for particular
-kinds of files.  Run `configure --help' for a list of the directories
-you can set and what kinds of files go in them.
-
-   If the package supports it, you can cause programs to be installed
-with an extra prefix or suffix on their names by giving `configure' the
-option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
-
-Optional Features
-=================
-
-   Some packages pay attention to `--enable-FEATURE' options to
-`configure', where FEATURE indicates an optional part of the package.
-They may also pay attention to `--with-PACKAGE' options, where PACKAGE
-is something like `gnu-as' or `x' (for the X Window System).  The
-`README' should mention any `--enable-' and `--with-' options that the
-package recognizes.
-
-   For packages that use the X Window System, `configure' can usually
-find the X include and library files automatically, but if it doesn't,
-you can use the `configure' options `--x-includes=DIR' and
-`--x-libraries=DIR' to specify their locations.
-
-Specifying the System Type
-==========================
-
-   There may be some features `configure' can not figure out
-automatically, but needs to determine by the type of host the package
-will run on.  Usually `configure' can figure that out, but if it prints
-a message saying it can not guess the host type, give it the
-`--host=TYPE' option.  TYPE can either be a short name for the system
-type, such as `sun4', or a canonical name with three fields:
-     CPU-COMPANY-SYSTEM
-
-See the file `config.sub' for the possible values of each field.  If
-`config.sub' isn't included in this package, then this package doesn't
-need to know the host type.
-
-   If you are building compiler tools for cross-compiling, you can also
-use the `--target=TYPE' option to select the type of system they will
-produce code for and the `--build=TYPE' option to select the type of
-system on which you are compiling the package.
-
-Sharing Defaults
-================
-
-   If you want to set default values for `configure' scripts to share,
-you can create a site shell script called `config.site' that gives
-default values for variables like `CC', `cache_file', and `prefix'.
-`configure' looks for `PREFIX/share/config.site' if it exists, then
-`PREFIX/etc/config.site' if it exists.  Or, you can set the
-`CONFIG_SITE' environment variable to the location of the site script.
-A warning: not all `configure' scripts look for a site script.
-
-Operation Controls
-==================
-
-   `configure' recognizes the following options to control how it
-operates.
-
-`--cache-file=FILE'
-     Use and save the results of the tests in FILE instead of
-     `./config.cache'.  Set FILE to `/dev/null' to disable caching, for
-     debugging `configure'.
-
-`--help'
-     Print a summary of the options to `configure', and exit.
-
-`--quiet'
-`--silent'
-`-q'
-     Do not print messages saying which checks are being made.  To
-     suppress all normal output, redirect it to `/dev/null' (any error
-     messages will still be shown).
-
-`--srcdir=DIR'
-     Look for the package's source code in directory DIR.  Usually
-     `configure' can determine that directory automatically.
-
-`--version'
-     Print the version of Autoconf used to generate the `configure'
-     script, and exit.
-
-`configure' also accepts some other, not widely useful, options.

-

-     59 Temple Place, Suite 330, Boston, MA 02111-1307, USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-The Free Software Foundation has exempted Bash from the requirement of
-Paragraph 2c of the General Public License.  This is to say, there is
-no requirement for Bash to print a notice when it is started
-interactively in the usual way.  We made this exception because users
-and standards expect shells not to print such messages.  This
-exception applies to any program that serves as a shell and that is
-based primarily on Bash as opposed to other GNU software.
-
-			    Preamble
-
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users.  This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it.  (Some other Free Software Foundation software is covered by
-the GNU Library General Public License instead.)  You can apply it to
-your programs, too.
-
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
-  To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
-  For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have.  You must make sure that they, too, receive or can get the
-source code.  And you must show them these terms so they know their
-rights.
-
-  We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
-  Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software.  If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
-  Finally, any free program is threatened constantly by software
-patents.  We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary.  To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-		    GNU GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-  0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License.  The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language.  (Hereinafter, translation is included without limitation in
-the term "modification".)  Each licensee is addressed as "you".
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
-  1. You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
-  2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-    a) You must cause the modified files to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    b) You must cause any work that you distribute or publish, that in
-    whole or in part contains or is derived from the Program or any
-    part thereof, to be licensed as a whole at no charge to all third
-    parties under the terms of this License.
-
-    c) If the modified program normally reads commands interactively
-    when run, you must cause it, when started running for such
-    interactive use in the most ordinary way, to print or display an
-    announcement including an appropriate copyright notice and a
-    notice that there is no warranty (or else, saying that you provide
-    a warranty) and that users may redistribute the program under
-    these conditions, and telling the user how to view a copy of this
-    License.  (Exception: if the Program itself is interactive but
-    does not normally print such an announcement, your work based on
-    the Program is not required to print an announcement.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
-    a) Accompany it with the complete corresponding machine-readable
-    source code, which must be distributed under the terms of Sections
-    1 and 2 above on a medium customarily used for software interchange; or,
-
-    b) Accompany it with a written offer, valid for at least three
-    years, to give any third party, for a charge no more than your
-    cost of physically performing source distribution, a complete
-    machine-readable copy of the corresponding source code, to be
-    distributed under the terms of Sections 1 and 2 above on a medium
-    customarily used for software interchange; or,
-
-    c) Accompany it with the information you received as to the offer
-    to distribute corresponding source code.  (This alternative is
-    allowed only for noncommercial distribution and only if you
-    received the program in object code or executable form with such
-    an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it.  For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable.  However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License.  Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
-  5. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Program or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
-  6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
-  7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded.  In such case, this License incorporates
-the limitation as if written in the body of this License.
-
-  9. The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time.  Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number.  If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation.  If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
-  10. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission.  For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this.  Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
-			    NO WARRANTY
-
-  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
-  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
-POSSIBILITY OF SUCH DAMAGES.
-
-		     END OF TERMS AND CONDITIONS
-
-	Appendix: How to Apply These Terms to Your New Programs
-
-  If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
-  To do so, attach the following notices to the program.  It is safest
-to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the program's name and a brief idea of what it does.>
-    Copyright (C) 19yy  <name of author>
-
-    This program is free software; you can redistribute it and/or modify
-    it under the terms of the GNU General Public License as published by
-    the Free Software Foundation; either version 2 of the License, or
-    (at your option) any later version.
-
-    This program is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
-    GNU General Public License for more details.
-
-    You should have received a copy of the GNU General Public License
-    along with this program; if not, write to the Free Software
-    Foundation, Inc., 59 Temple Place - Suite 330, Boston, MA 02111-1307, USA
-
-Also add information on how to contact you by electronic and paper mail.
-
-If the program is interactive, make it output a short notice like this
-when it starts in an interactive mode:
-
-    Gnomovision version 69, Copyright (C) 19yy name of author
-    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
-    This is free software, and you are welcome to redistribute it
-    under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License.  Of course, the commands you use may
-be called something other than `show w' and `show c'; they could even be
-mouse-clicks or menu items--whatever suits your program.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the program, if
-necessary.  Here is a sample; alter the names:
-
-  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
-  `Gnomovision' (which makes passes at compilers) written by James Hacker.
-
-  <signature of Ty Coon>, 1 April 1989
-  Ty Coon, President of Vice
-
-This General Public License does not permit incorporating your program into
-proprietary programs.  If your program is a subroutine library, you may
-consider it more useful to permit linking proprietary applications with the
-library.  If this is what you want to do, use the GNU Library General
-Public License instead of this License.

-may supply a profile to create custom workloads, while most other
-filesystem benchmarks use a fixed set of workloads.
-
-As of version 5.1, it supports seven different basic operations, support
-for multiple groups of threads with different operation mixtures,
-support for operation across multiple filesystems, and support for
-filesystem aging prior to benchmarking.
-
-
-Differences from version 4.0 and older:
-
-Version 5.0 and above represent almost a total re-write and many
-things have changed.  In version 5.0 and above FFSB moved to a
-time-regulated run versus doing a set number of different operations
-and timing the whole thing.  This is primarily to better deal with the
-use of multiple threadgroups which would otherwise not be synchronized
-at termination time.
-
-Additionally, the FFSB configuration file format has changed in
-version 5.0, although we do support old-style configuration files
-along with a run-time passed on the command line.  In this mode,
-version 5.0 and above ignores the iterations parameter, and simply
-uses the time specified on the command line.
-
-Behaviorally, most of the old operations are the same -- sequential
-reads and sequential writes work as they did before.  One change in
-version 5.0 is the skip-read behavior of reading then seeking forward
-a fixed amount then reading again is removed, we now support fully
-randomized reads and writes from random offsets within the file.
-
-Version 4.0 didn't support overwrites (only appends) so we interpret
-writes in old config files to be append operations.
-
-On Linux, CPU utilization information will only be accurate for
-systems using NPTL, older Linuxthreads systems will probably only see
-zeros for CPU utilization because Linuxthreads is non-compliant to
-POSIX. Version 4.0 and older could be recompiled to work on
-Linuxthreads, but in 5.0 and later we no longer support this.
-
-We no longer support the "outputfile" on the command line.
-
-One should simply use tee or similar to capture the output.  FFSB
-unbuffers standard out for this purpose, and errors are sent on
-standard error.
-
-Global options:
-
-There are eight valid global options placed at the beginning of the
-profile.  Three of them are required: num_filesystems (number of
-filesystems), num_threadgroups (number of threadgroups), and time
-(running time of the benchmark).  The other five options are:
-
-directio   - each call to open will be made using O_DIRECT
-alignio    - aligns all block operations for random reads and writes
-             on 4k boundaries.
-bufferedio - currently ignored: it is intended to use libc
-             fread,rwrite, instead of just unix read and write calls
-verbose    - currently ignored
-
-callout    - calls and external command and waits for its termination
-	     before FFSB begins the benchmark phase.
-	     This is useful for synchronizing distributed clients,
-	     starting profilers, etc.
-
-They must be specified in the above order (num_filesystems,
-num_threadgroups, time, directio, alignio, bufferedio, verbose,
-callout).
-
-
-
-Filesystems:
-
-Filesystems are specified to FFSB in the form of a directory.  FFSB
-assumes that the filesystem is mounted at this directory and will not
-do any verification of this fact beyond ensuring it can read/write to
-the location.  So be careful to ensure something with enough space to
-handle the dataset is in fact mounted at the specified location.
-
-In the filesystem clause of the profile, one may set the starting
-number of files and directories as well as a minimum and maximum
-filesize for the filesystem.  One may also specify the blocksize
-used for creating the files separately in the filesystem clause.
-
-Also, if a filesystem is to be aged, a special threadgroup clause may
-be embedded in a filesystem clause to specify the operation mixture
-and number of threads used to age the filesystem.  This threadgroup is
-run until filesystem utilization reaches the specified amount.
-
-Inheritance --  if you are using multiple filesystems, all attributes
-except the location should be inherited from the previous filesystem.
-This is done to make it easier to add groups of similar filesystems.
-In this case, only the location is required in the filesystem clause.
-
-As of version 5.1, filesystem re-use is supported if a given
-filesystem hasn't been modified beyond it's orginal specifications
-(number of files and directories is correct, and file sizes are within
-specifications).  This can be a huge time saver if one wishes to do
-multiple runs on the same data-set without altering it during a run,
-because the fileset doesn't need to be recreated before each run.
-
-To do this, specify "reuse=1" in the filesystem clause, and FFSB will
-verify the fileset first, and if it checks out it will use it.
-Otherwise, it will remove everything and re-create the filesets for
-that filesystem.
-
-Threadgroups:
-
-An arbitrary number of threadgroups with differing numbers of threads
-and operation mixes can be specified.  The operations are specified
-using a weighting for each operation, if an operation isn't specified
-it's weighting is assumed to be zero (not used).
-
-"Think-time" for a threadgroup may also be specified in millisecond
-amounts using the "op_delay" parameter, where every thread will wait
-for the specified amount between each operation.
-
-Operations:
-
-All operations begin by randomly selecting a filesystem from the list
-of filesystems specified in the profile.  The distribution aims to be
-uniform across all filesystems.
-
-
-The seven operations are:
-
-reads  - read() calls with an overall amount and a blocksize
-         operates on existing files.  Care must be taken to ensure
-         that the read amount is smaller than the size of any possible
-         file.
-
-	 If random_read is specified, then the each individual blocks
-         will be read starting from a random point with the file, and
-         this will continue until the entire amount specified has been
-         read.  This offset of each random block will be totally
-         random to the byte level, unless the "alignio" global parameter
-         is on, and then the reads will be 4096 byte aligned.  This is
-         generally recommended.
-
-
-readall - Very similar to read above, except it doesn't take an
-          amount; it simply reads the entire file sequentially using the
-          read_blocksize.   This is useful for situations where
-	  different filesystems have differently sized files, and sequential
-	  read patterns across all filesystems are desired.
-
-writes - write() calls with an overall amount and blocksize
-         this is an overwrite operation and will not enlarge an existing
-         file, again one must be careful not to specify a write amount
-         that is larger than any possible file in the data set.
-
-	 If random_write is specified, then the each individual blocks
-         will be written starting from a random point with the file, and
-         this will continue until the entire amount specified has been
-         written out.  This offset of each random block will be totally
-         random to the byte level, unless the "alignio" global parameter
-         is on, and then the writes will be 4096 byte aligned.  This
-         is generally recommended.
-
-	 If the fsync_flag parameter for the threadgroup is non-zero,
-	 then after all of the write calls are finished, fsync() will
-	 be called on the file descriptor before the file is closed.
-
-
-creates - creates a file using open() call and determines the size
-          randomly between on the constraints (min_filesize and
-          max_filesize) for the selected filesystem. Write operations will
-          be done using the same blocksize as is specified for the
-          write operation.
-deletes - calls unlink() on a filename and removes it from the
-          internal data-structures.  One must be careful to ensure
-          there are enough files to delete at all times or else the benchmark
-          will terminate.
-appends - calls write() using the append flag with an overall amount
-          and a blocksize to be appended onto a randomly chosen file.
-metas   - this is actually a mix of several different directory
-          operations.  Each "meta" operation consists of two directory
-          creates, one directory remove, and a directory rename.
-          These operations are all carried out separately from the
-          other 5 operations.
-
-Operation accounting:
-
-Each operation which uses a blocksize counts each read/write of a
-blocksize as an operation (reads,writes,creates, and appends) whereas
-deletes and metas are considered single operations.
-
-Running the benchmark:
-
-There are three phases to running the benchmark, aging, fileset
-creates, and the benchmark phase.
-
-The create phase is carried out across all filesystems simultaneously
-with one dedicated thread per filesystem.
-
-After the create phase, sync() is called to ensure all dirty data gets
-written out before the benchmark phase begins, and sync() is again
-called at the end of the benchmark phase.  The time in sync() at the
-end of the benchmark phase is counted as part of the benchmark phase.
-
-Caveats/Holes/Bugs:
-
-Aging and aging across multiple filesystems simultaneously hasn't been tested
-very much.
-
-If *any* i/o operation or system call/libc call fails, the benchmark
-will terminate immediately.
-
-The parser doesn't handle mal-formed or incorrect profiles very well
-(or at all).
-
-The parser doesn't check to make sure all of the appropriate options
-have been specified.  For example, if writes are specified in a
-threadgroup but write_blocksize isn't specified, the parse won't catch
-it, but the benchmark run will fail later on.
-
-
-Configuration Files (new style):
-
-New Style Configuration allows for arbitrary newlines between lines,
-and comments using '#' at the start of a line.  Also it allows tabs,
-whitespace before and after configuration parameters.
-
-The new style configuration file is broken up into three main parts:
-
-global parameters, filesystems, and threadgroups
-
-The sections must be in the above order.
-
-Global parameters:
-
-Global parameters are described above, the first three are always
-required. Example:
-
-----------
-
-num_filesystems=1
-num_threadgroups=1
-time=30 		# time is in seconds
-
-directio=0 		# don't use direct io
-alignio=1  		# align random IOs to 4k
-bufferedio=0		# this does nothing right now
-verbose=0		# this does nothing right now
-
-			# calls and external command and waits
-			# everything until the newline is taken
-			# so you can have abritrary parmeters
-callout=synchronize.sh myhostname
-
----------
-
-All of these must appear in this order, though you can leave out the
-optional ones.
-
-Filesystems:
-
-Filesystems describe different logical sets of files residing in
-different directorys.  There is no strict requirement that they
-actually be on different filesystems, only that the directory
-specified already exists.
-
-Filesystems are specified by a clause with a filesystem number like
-this:
-
-[filesystem0]
-	location=/mnt/testing/
-	num_files=10
-	num_dirs=1
-	max_filesize=4096
-	min_filesize=4096
-[end0]
-
-
-The clause must always begin with [filesystemX] and end with [endX]
-where X is the number of that filesystem.
-
-You should start wiht X = 0, and increment by one for each following
-filesystem.  If they are out of order, things will likely break.
-
-The required information for each filesystem is: location, num_files,
-num_dirs, max_filesize, and min_filesize.  Beyond those the following
-four options are supported:
-
-
-
-reuse=1 # check the filesystem to see if it is reusable
-
-	# filesystem aging, three components required
-	# takes agefs=1 to turn it on
-	# then a valid threadgroup specification
-	# then a desired utilization percentage
-
-agefs=1 # age the filesystem according to the following threadgroup
-	[threadgroup0]
-		num_threads=10
-		write_size=40960
-		write_blocksize=4096
-		create_weight=10
-		append_weight=10
-		delete_weight=1
-	[end0]
-desired_util=0.20	# In this case, age until the fs is 20% full
-
-create_blocksize=4096   # specify the blocksize to write()
-		        # for creating the fileset, defaults to 4096
-
-age_blocksize=4096      # specify the blocksize to write() for aging
-
-
-Also, to allow lazy people to use lots of filesystems, we support
-filesystem inheritance, which simply copies all options but the
-location from the previous filesystem clause if nothing is specified.
-Obviously, this doesn't work for filesystem0. (May not work for aging
-either?)
-
-Full blown filesystem clause example:
-
-----
-
-[filesystem0]
-
-	# required parts
-
-	location=/home/sonny/tmp
-	num_files=100
-	num_dirs=100
-	max_filesize=65536
-	min_filesize=4096
-
-	# aging part
-	agefs=0
-	[threadgroup0]
-		num_threads=10
-		write_size=40960
-		write_blocksize=4096
-		create_weight=10
-		append_weight=10
-		delete_weight=1
-	[end0]
-		desired_util=0.02	# age until 2% full
-
-	# other optional commands
-
-	create_blocksize=1024		# use a small create blocksize
-	age_blocksize=1024		# and smaller age create blocksize
-	reuse=0	                        # don't reuse it
-[end0]
-
-
-
---
-
-Threadgroups:
-
-Threadgropus are very similar to filesystems in that any number of
-them can be specified in clauses, and they must be in order starting
-with threadgroup0.
-
-Example:
-
----
-
-[threadgroup0]
-	num_threads=32
-	read_weight=4
-	append_weight=1
-
-	write_size=4096
-	write_blocksize=4096
-
-	read_size=4096
-	read_blocksize=4096
-[end0]
-
----
-
-In a threadgroup clause, num_threads is required and must be at least
-1.  Then, at least one operation must be given a weight greater than 0
-to be a valid threadgroup.  Operations can be given a weighting of 0,
-and in this case they are ignored.
-
-Certain operations will also require other commands, for example, if
-read_weight is greater than zero, then one must also include a
-read_size and a read_blocksize.  Here's the table of requirements and
-options:
-
-
-Operation		Requirements			Options
---			--				--
-read_weight		read_size, read_blocksize	read_random
-readall_weight		read_blocksize			none
-write_weight		write_size, write_blocksize	write_random,fsync_file
-create_weight		write_blocksize or create_blocksize	none
-append_weight		write_blocksize, write_size	none
-delete_weight		none				none
-meta_weight		none				none
-
-
-
-Other threadgroup options:
-
-op_delay=10  # specify a wait between operations in milli-seconds
-
-bindfs=3     # This allows you to restrict a threadgroup's operation
-             # to a specific filesystem number.  Currently only
-	     # binding to one specific filesystem is supported

-# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
-# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
-# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
-#
-# Of course, Automake must honor this variable whenever it calls a
-# tool from the auxiliary directory.  The problem is that $srcdir (and
-# therefore $ac_aux_dir as well) can be either absolute or relative,
-# depending on how configure is run.  This is pretty annoying, since
-# it makes $ac_aux_dir quite unusable in subdirectories: in the top
-# source directory, any form will work fine, but in subdirectories a
-# relative path needs to be adjusted first.
-#
-# $ac_aux_dir/missing
-#    fails when called from a subdirectory if $ac_aux_dir is relative
-# $top_srcdir/$ac_aux_dir/missing
-#    fails if $ac_aux_dir is absolute,
-#    fails when called from a subdirectory in a VPATH build with
-#          a relative $ac_aux_dir
-#
-# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
-# are both prefixed by $srcdir.  In an in-source build this is usually
-# harmless because $srcdir is `.', but things will broke when you
-# start a VPATH build or use an absolute $srcdir.
-#
-# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,

-# This will work as long as MISSING is not called from configure, because

-# However there are other variables, like CC, which are often used in
-# configure, and could therefore not use this "fixed" $ac_aux_dir.

-# AM_PROG_INSTALL_STRIP
-# ---------------------
-# One issue with vendor `install' (even GNU) is that you can't
-# specify the program used to strip binaries.  This is especially
-# annoying in cross-compiling environments, where the build's strip
-# is unlikely to handle the host's binaries.
-# Fortunately install-sh will honor a STRIPPROG variable, so we
-# always use install-sh in `make install-strip', and initialize
-# STRIPPROG with the value of the STRIP variable (set by the user).
-AC_DEFUN([AM_PROG_INSTALL_STRIP],
-[AC_REQUIRE([AM_PROG_INSTALL_SH])dnl
-# Installed binaries are usually stripped using `strip' when the user
-# run `make install-strip'.  However `strip' might not be the right
-# tool to use in cross-compilation environments, therefore Automake
-# will honor the `STRIP' environment variable to overrule this program.
-dnl Don't test for $cross_compiling = yes, because it might be `maybe'.

-
-Usage: $0 [OPTION]... [VAR=VALUE]...
-
-To assign environment variables (e.g., CC, CFLAGS...), specify them as
-VAR=VALUE.  See below for descriptions of some of the useful variables.
-
-Defaults for the options are specified in brackets.
-
-Configuration:
-  -h, --help              display this help and exit
-      --help=short        display options specific to this package
-      --help=recursive    display the short help of all the included packages
-  -V, --version           display version information and exit
-  -q, --quiet, --silent   do not print \`checking...' messages
-      --cache-file=FILE   cache test results in FILE [disabled]
-  -C, --config-cache      alias for \`--cache-file=config.cache'
-  -n, --no-create         do not create output files
-      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
-
-Installation directories:
-  --prefix=PREFIX         install architecture-independent files in PREFIX
-			  [$ac_default_prefix]
-  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
-			  [PREFIX]
-
-By default, \`make install' will install all the files in
-\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
-an installation prefix other than \`$ac_default_prefix' using \`--prefix',
-for instance \`--prefix=\$HOME'.
-
-For better control, use the options below.
-
-Fine tuning of the installation directories:
-  --bindir=DIR           user executables [EPREFIX/bin]
-  --sbindir=DIR          system admin executables [EPREFIX/sbin]

-  --enable-dependency-tracking   do not reject slow dependency extractors
-
-Some influential environment variables:
-  CC          C compiler command
-  CFLAGS      C compiler flags
-  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
-              nonstandard directory <lib dir>
-  LIBS        libraries to pass to the linker, e.g. -l<library>

-  CPP         C preprocessor
-
-Use these variables to override the choices made by `configure' or to help
-it to find libraries and programs with nonstandard names/locations.

- *  A thread group contains configuration information and can run its
- *  "gang" of threads performing a particular mix of operations.
- *
- * The thread group is responsible for creating the ffsb_thread
- * objects which must ask the thread group object to select an
- * operation and a filesystem to run that operation on.  The thread
- * objects don't contain any of the configuration information.
- *
- * Thread groups are also abstracted so they can be "run" arbitrarily
- * which is useful because we can reuse them for aging.  The running
- * is a bit complex, the thread group has to have a callback function
- * which is runs at a specified interval to determine when to
- * terminate.
- *
- * To synchronize starting across many thread groups there are two
- * barriers used, the first one "tg_barrier" in the run_params is to
- * synchronize multiple thread-groups being ready to start, meaning
- * that all their threads have been spawned The second one
- * "thread_barrier" synchronizes all threads across multiple thread
- * groups, so that they all start at once.
