[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)
