The rmapbt repair code plays some dirty tricks with the fs freezer to avoid running afoul of regular xfs locking requirements. Add a test to check that filesystem write activities do not deadlock with the repair program. Signed-off-by: Darrick J.

# Race freeze and rmapbt repair for a while to see if we crash or livelock.
|
|
# rmapbt repair requires us to freeze the filesystem to stop all filesystem
|
|
# activity, so we can't have userspace wandering in and thawing it.
