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 --- Commits in this patchset: * xfs: reduce the rate of cond_resched calls inside scrub * xfs: move xfs_ioc_scrub_metadata to scrub.c * xfs: introduce vectored scrub mode * xfs: only iget the file once when doing vectored scrub-by-handle --- fs/xfs/libxfs/xfs_fs.h | 33 +++++++ fs/xfs/scrub/common.h | 25 ----- fs/xfs/scrub/scrub.c | 223 ++++++++++++++++++++++++++++++++++++++++++++++ fs/xfs/scrub/scrub.h | 64 +++++++++++++ fs/xfs/scrub/trace.h | 79 ++++++++++++++++ fs/xfs/scrub/xfarray.c | 10 +- fs/xfs/scrub/xfarray.h | 3 + fs/xfs/scrub/xfile.c | 2 fs/xfs/scrub/xfs_scrub.h | 6 + fs/xfs/xfs_ioctl.c | 26 ----- 10 files changed, 412 insertions(+), 59 deletions(-)
