Hi all, Create a vectorized version of the metadata scrub and repair ioctl, and adapt xfs_scrub to use that. This is an experiment to measure overhead and to try refactoring xfs_scrub. If you're going to start using this code, I strongly recommend pulling from my git trees, which are linked below. This has been running on the djcloud for months with no problems. Enjoy! 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=vectorized-scrub xfsprogs git tree: https://git.kernel.org/cgit/linux/kernel/git/djwong/xfsprogs-dev.git/log/?h=vectorized-scrub fstests git tree: https://git.kernel.org/cgit/linux/kernel/git/djwong/xfstests-dev.git/log/?h=vectorized-scrub --- io/scrub.c | 371 ++++++++++++++++++++++++++++++---- libfrog/fsgeom.h | 6 + libfrog/scrub.c | 124 +++++++++++ libfrog/scrub.h | 4 libxfs/xfs_fs.h | 10 + libxfs/xfs_fs_staging.h | 32 +++ man/man2/ioctl_xfs_scrubv_metadata.2 | 168 +++++++++++++++ man/man8/xfs_io.8 | 51 +++++ scrub/phase1.c | 2 scrub/phase2.c | 93 +++++++-- scrub/phase3.c | 84 ++++++-- scrub/repair.c | 354 ++++++++++++++++++++------------ scrub/scrub.c | 348 ++++++++++++++++++++++++-------- scrub/scrub.h | 19 ++ scrub/scrub_private.h | 62 ++++-- 15 files changed, 1422 insertions(+), 306 deletions(-) create mode 100644 man/man2/ioctl_xfs_scrubv_metadata.2
