From: Darrick J. Wong <djwong@xxxxxxxxxx>
Check the dirents in metadata directories for problems and repair them
if necessary. Also make sure that the sb-rooted inodes (root, metadir
root, rt bitmap, rt summary) are always allocated in that order.
Note that xfs_repair will always rebuild the metadata directory tree
itself, so we only need to report problems, not fix them.
