These patches improve ext4's shutdown handling.  Most of the problems
that show up when running generic/388 with a single CPU have been
addressed.  (There are still problems when running with 2 or more
CPU's.)

Theodore Ts'o (7):
  ext4: add tracepoints for shutdown and file system errors
  jbd2: clarify bad journal block checksum message
  ext4: shutdown should not prevent get_write_access
  ext4: eliminate sleep from shutdown ioctl
  ext4: pass -ESHUTDOWN code to jbd2 layer
  jbd2: if the journal is aborted then don't allow update of the log
    tail
  ext4: don't update checksum of new initialized bitmaps
