use XFS_CORRUPTION_ERROR in xfs_btree_check_sblock
In Red Hat Bug 512552
- Can't write to XFS mount during raid5 resync
a user ran into corruption while resyncing a raid, and we failed
a consistency test, but didn't get much more info; it'd be nice
to call XFS_CORRUPTION_ERROR here so we can see the buffer
contents.
