Merge tag 'btree-hoist-scrub-checks-6.4_2023-04-11' of git://git.kernel.org/pub/scm/linux/kernel/git/djwong/xfs-linux into guilt/xfs-for-next
xfs: hoist scrub record checks into libxfs [v24.5] There are a few things about btree records that scrub checked but the libxfs _get_rec functions didn't. Move these bits into libxfs so that everyone can benefit. Signed-off-by: Darrick J. Wong <djwong@kernel.org> Signed-off-by: Dave Chinner <david@fromorbit.com>
