Darrick J. Wong 6c7289528d xfs: abort directory parent scrub scans if we encounter a zapped directory ... In a previous patch, we added some code to perform sufficient repairs to an ondisk inode record such that the inode cache would be willing to load the inode. If the broken inode was a shortform directory, it will reset the directory to something plausible, which is to say an empty subdirectory of the root. The telltale signs that something is seriously wrong is the broken link count. Such directories look clean, but they shouldn't participate in a filesystem scan to find or confirm a directory parent pointer. Create a predicate that identifies such directories and abort the scrub. Found by fuzzing xfs/1554 with multithreaded xfs_scrub enabled and u3.bmx[0].startblock = zeroes. Signed-off-by: Darrick J.
