Merge tag 'for-6.4-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux
Pull btrfs updates from David Sterba: "Mostly core changes and cleanups, some notable fixes and two performance improvements in directory logging. The IO path cleanups are removing or refactoring old code, scrub main loop has been completely rewritten also refactoring old code. There are some changes to non-btrfs code, mostly trivial, the cgroup punt bio logic is only moved from generic code. Performance improvements: - improve logging changes in a directory during one transaction, avoid iterating over items and reduce lock contention (fsync time 4x lower) - when logging directory entries during one transaction, reduce locking of subvolume trees by checking tree-log instead (improvement in throughput and latency for concurrent access to a subvolume) Notable fixes: - dev-replace: - properly honor read mode when requested to avoid reading from source device - target device won't be used for eventual read repair, this is unreliable for NODATASUM files - when there are unpaired (and unrepairable) metadata during replace, exit early with error and don't try to finish whole operation - scrub ioctl properly rejects unknown flags - fix global block reserve calculations - fix partial direct io write when there's a page fault in the middle, iomap will try to continue with partial request but the btrfs part did not match that, this can lead to zeros written instead of data Core changes: - io path: - continued cleanups and refactoring around bio handling - extent io submit path simplifications and cleanups - flush write path simplifications and cleanups - rework logic of passing sync mode of bio, with further cleanups - rewrite scrub code flow, restructure how the stripes are enumerated and verified in a more unified way - allow to set lower threshold for block group reclaim in debug mode to aid zoned mode testing - remove obsolete time-based delayed ref throttling logic when truncating items - DREW locks are not using percpu variables anymore - more warning fixes (-Wmaybe-uninitialized) - u64 division simplifications - error handling improvements Non-btrfs code changes: - push cgroup punt bio logic to btrfs code (there was no other user of that), the functionality can be now selected separately by BLK_CGROUP_PUNT_BIO - crc32c_impl removed after removing last uses in btrfs code - add btrfs_assertfail() to objtool table" * tag 'for-6.4-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux: (147 commits) btrfs: mark btrfs_assertfail() __noreturn btrfs: fix uninitialized variable warnings btrfs: use log root when iterating over index keys when logging directory btrfs: avoid iterating over all indexes when logging directory btrfs: dev-replace: error out if we have unrepaired metadata error during btrfs: remove pointless loop at btrfs_get_next_valid_item() btrfs: scrub: reject unsupported scrub flags btrfs: reinterpret async discard iops_limit=0 as no delay btrfs: set default discard iops_limit to 1000 btrfs: remove unused raid56 functions which were dedicated for scrub btrfs: scrub: remove scrub_bio structure btrfs: scrub: remove scrub_block and scrub_sector structures btrfs: scrub: remove the old scrub recheck code btrfs: scrub: remove the old writeback infrastructure btrfs: scrub: remove scrub_parity structure btrfs: scrub: use scrub_stripe to implement RAID56 P/Q scrub btrfs: scrub: switch scrub_simple_mirror() to scrub_stripe infrastructure btrfs: scrub: introduce helper to queue a stripe for scrub btrfs: scrub: introduce error reporting functionality for scrub_stripe btrfs: scrub: introduce a writeback helper for scrub_stripe ...
