Wong Source kernel commit: df866c538ff098baa210b407b822818a415a6e7e 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.) Signed-off-by: Darrick J.
