Hi all, This series replaces all the open-coded integer division and multiplication conversions between rt blocks and rt extents with calls to static inline helpers. Having cleaned all that up, the helpers are augmented to skip the expensive operations in favor of bit shifts and masking if the rt extent size is a power of two. v1.1: various cleanups suggested by hch If you're going to start using this code, I strongly recommend pulling from my git trees, which are linked below. With a bit of luck, this should all go splendidly. Comments and questions are, as always, welcome. --D kernel git tree: https://git.kernel.org/cgit/linux/kernel/git/djwong/xfs-linux.git/log/?h=refactor-rt-unit-conversions-6.7 --- fs/xfs/libxfs/xfs_bmap.c | 20 +++--- fs/xfs/libxfs/xfs_rtbitmap.c | 4 + fs/xfs/libxfs/xfs_rtbitmap.h | 125 ++++++++++++++++++++++++++++++++++++++++ fs/xfs/libxfs/xfs_sb.c | 2 + fs/xfs/libxfs/xfs_trans_resv.c | 3 + fs/xfs/scrub/inode.c | 3 + fs/xfs/scrub/rtbitmap.c | 18 ++---- fs/xfs/scrub/rtsummary.c | 4 + fs/xfs/xfs_bmap_util.c | 38 +++++------- fs/xfs/xfs_fsmap.c | 13 ++-- fs/xfs/xfs_inode_item.c | 3 + fs/xfs/xfs_ioctl.c | 5 +- fs/xfs/xfs_linux.h | 12 ++++ fs/xfs/xfs_mount.h | 2 + fs/xfs/xfs_rtalloc.c | 4 + fs/xfs/xfs_super.c | 3 + fs/xfs/xfs_trans.c | 7 ++ 17 files changed, 200 insertions(+), 66 deletions(-)
