From: Darrick J. Wong <djwong@xxxxxxxxxx>
Allow the V5 bulkstat ioctl to return information about metadata
directory files so that xfs_scrub can find and scrub them, since they
are otherwise ordinary directories.
(Metadata files of course require per-file scrub code and hence do not
need exposure.)
