Hi Chandan, Please pull this branch with changes for xfs for 6.10-rc1. As usual, I did a test-merge with the main upstream branch as of a few minutes ago, and didn't see any conflicts. Please let me know if you encounter any problems. --D The following changes since commit c77b37584c2d1054452853e47e42c7350b8fe687: xfs: introduce vectored scrub mode (2024-04-23 16:55:18 -0700) are available in the Git repository at: https://git.kernel.org/pub/scm/linux/kernel/git/djwong/xfs-linux.git tags/reduce-scrub-iget-overhead-6.10_2024-04-23 for you to fetch changes up to 4ad350ac58627bfe81f71f43f6738e36b4eb75c6: xfs: only iget the file once when doing vectored scrub-by-handle (2024-04-23 16:55:18 -0700) ---------------------------------------------------------------- xfs: reduce iget overhead in scrub [v13.4 8/9] This patchset looks to reduce iget overhead in two ways: First, a previous patch conditionally set DONTCACHE on inodes during xchk_irele on the grounds that we knew better at irele time if an inode should be dropped. Unfortunately, over time that patch morphed into a call to d_mark_dontcache, which resulted in inodes being dropped even if they were referenced by the dcache. This actually caused *more* recycle overhead than if we'd simply called xfs_iget to set DONTCACHE only on misses. The second patch reduces the cost of untrusted iget for a vectored scrub call by having the scrubv code maintain a separate refcount to the inode so that the cache will always hit. This has been running on the djcloud for months with no problems. Enjoy! Signed-off-by: Darrick J. Wong <djwong@xxxxxxxxxx> ---------------------------------------------------------------- Darrick J.
