Merge tag 'xfs-cleanups-6.10_2024-05-02' of https://git.kernel.org/pub/scm/linux/kernel/git/djwong/xfs-linux into xfs-6.10-mergeF
xfs: last round of cleanups for 6.10 Here are the reviewed cleanups at the head of the fsverity series. Apparently there's other work that could use some of these things, so let's try to get it in for 6.10. Signed-off-by: Darrick J. Wong <[email protected]> Signed-off-by: Chandan Babu R <[email protected]> * tag 'xfs-cleanups-6.10_2024-05-02' of https://git.kernel.org/pub/scm/linux/kernel/git/djwong/xfs-linux: xfs: widen flags argument to the xfs_iflags_* helpers xfs: minor cleanups of xfs_attr3_rmt_blocks xfs: create a helper to compute the blockcount of a max sized remote value xfs: turn XFS_ATTR3_RMT_BUF_SPACE into a function xfs: use unsigned ints for non-negative quantities in xfs_attr_remote.c
