Merge tag 'xfs-4.16-merge-5' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
Pull more xfs updates from Darrick Wong: "As promised, here's a (much smaller) second pull request for the second week of the merge cycle. This time around we have a couple patches shutting off unsupported fs configurations, and a couple of cleanups. Last, we turn off EXPERIMENTAL for the reverse mapping btree, since the primary downstream user of that information (online fsck) is now upstream and I haven't seen any major failures in a few kernel releases. Summary: - Print scrub build status in the xfs build info. - Explicitly call out the remaining two scenarios where we don't support reflink and never have. - Remove EXPERIMENTAL tag from reverse mapping btree!" * tag 'xfs-4.16-merge-5' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: xfs: remove experimental tag for reverse mapping xfs: don't allow reflink + realtime filesystems xfs: don't allow DAX on reflink filesystems xfs: add scrub to XFS_BUILD_OPTIONS xfs: fix u32 type usage in sb validation function
