Hi all, Create a vectorized version of the metadata scrub and repair ioctl, and adapt xfs_scrub to use that. This mitigates the impact of system call overhead on xfs_scrub runtime. 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-6.10 --- 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 --- fs/xfs/libxfs/xfs_fs.h | 33 +++++++++ fs/xfs/scrub/common.h | 25 ------ fs/xfs/scrub/scrub.c | 177 ++++++++++++++++++++++++++++++++++++++++++++++ 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, 366 insertions(+), 59 deletions(-)
