Merge tag 'for-6.5-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux
Pull btrfs updates from David Sterba: "Mainly core changes, refactoring and optimizations. Performance is improved in some areas, overall there may be a cumulative improvement due to refactoring that removed lookups in the IO path or simplified IO submission tracking. Core: - submit IO synchronously for fast checksums (crc32c and xxhash), remove high priority worker kthread - read extent buffer in one go, simplify IO tracking, bio submission and locking - remove additional tracking of redirtied extent buffers, originally added for zoned mode but actually not needed - track ordered extent pointer in bio to avoid rbtree lookups during IO - scrub, use recovered data stripes as cache to avoid unnecessary read - in zoned mode, optimize logical to physical mappings of extents - remove PageError handling, not set by VFS nor writeback - cleanups, refactoring, better structure packing - lots of error handling improvements - more assertions, lockdep annotations - print assertion failure with the exact line where it happens - tracepoint updates - more debugging prints Performance: - speedup in fsync(), better tracking of inode logged status can avoid transaction commit - IO path structures track logical offsets in data structures and does not need to look it up User visible changes: - don't commit transaction for every created subvolume, this can reduce time when many subvolumes are created in a batch - print affected files when relocation fails - trigger orphan file cleanup during START_SYNC ioctl Notable fixes: - fix crash when disabling quota and relocation - fix crashes when removing roots from drity list - fix transacion abort during relocation when converting from newer profiles not covered by fallback - in zoned mode, stop reclaiming block groups if filesystem becomes read-only - fix rare race condition in tree mod log rewind that can miss some btree node slots - with enabled fsverity, drop up-to-date page bit in case the verification fails" * tag 'for-6.5-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux: (194 commits) btrfs: fix race between quota disable and relocation btrfs: add comment to struct btrfs_fs_info::dirty_cowonly_roots btrfs: fix race when deleting free space root from the dirty cow roots list btrfs: fix race when deleting quota root from the dirty cow roots list btrfs: tracepoints: also show actual number of the outstanding extents btrfs: update i_version in update_dev_time btrfs: make btrfs_compressed_bioset static btrfs: add handling for RAID1C23/DUP to btrfs_reduce_alloc_profile btrfs: scrub: remove btrfs_fs_info::scrub_wr_completion_workers btrfs: scrub: remove scrub_ctx::csum_list member btrfs: do not BUG_ON after failure to migrate space during truncation btrfs: do not BUG_ON on failure to get dir index for new snapshot btrfs: send: do not BUG_ON() on unexpected symlink data extent btrfs: do not BUG_ON() when dropping inode items from log root btrfs: replace BUG_ON() at split_item() with proper error handling btrfs: do not BUG_ON() on tree mod log failures at btrfs_del_ptr() btrfs: do not BUG_ON() on tree mod log failures at insert_ptr() btrfs: do not BUG_ON() on tree mod log failure at insert_new_root() btrfs: do not BUG_ON() on tree mod log failures at push_nodes_for_insert() btrfs: abort transaction at update_ref_for_cow() when ref count is zero ...
