Any suggestion how to fix? TIA, Andreas

Does the function really needs to be called qemu_vmalloc? If not, having the same name for two different things is bad. Paolo

Right now there isn't even a matching qemu_vfree(); the implementation in util/oslib-posix.c would be used and that would use free() instead of munmap(). So, code that happened to use qemu_vmalloc() outside bsd-user would be completely wrong. It was a time bomb, and it's a good thing that it was exposed. Paolo
The following changes since commit 63fb2590839162afdf14d7c0ee02d460766c0956: Merge branch 'target-arm.next' of git://git.linaro.org/people/pmaydell/qemu-arm (2013-01-12 12:47:07 +0000) are available in the git repository at: git://github.com/bonzini/qemu.git stub for you to fetch changes up to b8f962d919682b9d2b5320315989d0c16ba33cbe: build: improve quiet output for .stp rules (2013-01-12 17:57:40 +0100) This is a light version of the source reorganization I proposed last September. While working on it I noticed that a useful part to start from was the utility routines, because this helps identifying missing unit tests and modularity problems. Also, these files are relatively rarely changed. Hence, moving them will not complicate backports to stable branches, and will make the "action" more visible to anyone casually observing the tree. Hence, this is where this series starts from. After this series, the top directory has about 80 *.c and *.h files, down from over 250 in 1.3.0, which is already a fine improvement. Patch 1 makes qemu-config.c more modular: there is no need for tools to host the description of QEMU's command-line options. Patch 2 finishes the transition to libqemustub.a, removing qemu-tool.c and qemu-user.c. Patches 3 to 13 are a longish digression in libcacard, improving support for libtool in the build system and simplifying the integration between libcacard's build rules and the rest of the Makefiles. Also, vscclient is now linked to the dynamic library so that missing symbols (like the one fixed in patch 7) are caught early. (QEMU still duplicates the code; I'd fear for my physical integrity if I forced people to write "libtool --mode=execute gdb" instead of just "gdb"). Patches 14 to 22 create a new static library libqemuutil.a, whose component files all come from subdirectories of the top tree directory: qobject, util, qapi. Using a static library helps putting the number of *-obj-y variables on a diet, and limits the duplication in the Makefile rules. Patches 23 and 24 further limit the number and nesting of *-obj-y variables. Finally, patches 25 to 27 affect tracing, which is also moved to libqemuutil.a. Patch 25 is Lluis's already posted patch to introduce trace/Makefile.objs. Only build-tested on Win32. v1->v2: Rebased. ---------------------------------------------------------------- Alon Levy (1): libcacard: fix missing symbol in libcacard.so Paolo Bonzini (26): qemu-option: move standard option definitions out of qemu-config.c stubs: fully replace qemu-tool.c and qemu-user.c build: make libtool verbose when making with V=1 build: support linking with libtool objects/libraries build: move dtrace rules to rules.mak build: remove CONFIG_SMARTCARD libcacard: require libtool to build it libcacard: prepare to use -y trick in the Makefile libcacard: use per-target variable definitions libcacard: add list of exported symbols libcacard: rewrite Makefile in non-recursive style libcacard: link vscclient to dynamic library libcacard: list oslib-obj-y file explicitly build: rename oslib-obj-y to util-obj-y build: move util-obj-y to libqemuutil.a build: move files away from tools-obj-y, common-obj-y, user-obj-y build: move libqemuutil.a components to util/ build: move qobject files to qobject/ and libqemuutil.a build: consolidate multiple variables into universal-obj-y build: move QAPI definitions for QEMU out of qapi-obj-y build: move base QAPI files to libqemuutil.a build: move version-obj-y to the generic LINK rule build: remove coroutine-obj-y build: some simplifications for "trace/Makefile.objs" build: fold trace-obj-y into libqemuutil.a build: improve quiet output for .stp rules Makefile | 57 +- Makefile.objs | 128 +-- Makefile.target | 17 +- block/iscsi.c | 27 + blockdev.c | 118 +++ configure | 85 +- exec.c | 2 +- fsdev/Makefile.objs | 1 + fsdev/qemu-fsdev-dummy.c | 7 -
