Hi Dave, et. al., This is the 6.3-rc2 rebase of all the online repair code, all the way to the end of part 1. Since the 6.2 deluge, I've incorporated the bits of feedback I've already received. Initial QA of these two deluges completed last Friday, though there are some lingering reclaim hangs in 6.3 ... oddly *after* the VM has unmounted the filesystem. I have also restructured the directory and parent pointer repair code to match more closely the fully-fleshed versions that will appear as part 2 of online repair, in the parent pointers patchset. This enables me to use this branch to QA all the stuff around directory rebuilding (atomic extent swapping, reaping, etc.) and my fork of Allison's branch to QA the directory scanning part without having to port even more of part 1. Speaking of which, I've finished rebasing my fork of the parent pointers patchset, and it is undergoing testing as we speak. --D The following changes since commit 5023db0fd78213c4d9a5e6c027c6f9b55dc1fdc9: xfs: cross-reference rmap records with refcount btrees (2023-03-14 17:44:07 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/djwong/xfs-linux.git tags/xfile-page-caching_2023-03-14 for you to examine changes up to 67bb67e9a9941400f950d75d77991bf99c54ed05: xfile: implement write caching (2023-03-14 17:44:26 -0700) ---------------------------------------------------------------- xfs: cache xfile pages for better performance This patchset improves the performance of xfile-backed btrees by teaching the buffer cache to directly map pages from the xfile. It also speeds up xfarray operations substantially by implementing a small page cache to avoid repeated kmap/kunmap calls. Collectively, these can reduce the runtime of online repair functions by twenty percent or so. Signed-off-by: Darrick J.
