On upstream kernel, running some tests which corrupt XFS on purpose
got the mismatched output. e.g. running xfs/087:
------------------------------------------------
+ check fs
+ corrupt image
+ mount image
-+ modify files
-broken: 1
+ repair fs
+ mount image (2)
------------------------------------------------
It is reasonable for corrupted XFS to be caught and rejected by mount
or read/write operation.

Targeted fuzzing tests which destroy various pieces of directory
metadata; the tests look for (a) kernel detection of corruption, (b)
xfs_repair repair of said corruption, and (c) post-repair fs
usability.
