[PATCH] Revert bd_mount_mutex back to a semaphore
Revert bd_mount_mutex back to a semaphore so that xfs_freeze -f /mnt/newtest; xfs_freeze -u /mnt/newtest works safely and doesn't produce lockdep warnings. (XFS unlocks the semaphore from a different task, by design. The mutex code warns about this) Signed-off-by: Dave Chinner <dgc@sgi.com> Cc: Ingo Molnar <mingo@elte.hu> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
