Merge tag 'for-6.10-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux
Pull btrfs updates from David Sterba: "This update brings a few minor performance improvements, otherwise there's a lot of refactoring, cleanups and other sort of not user visible changes. Performance improvements: - inline b-tree locking functions, improvement in metadata-heavy changes - relax locking on a range that's being reflinked, allows read operations to run in parallel - speed up NOCOW write checks (throughput +9% on a sample test) - extent locking ranges have been reduced in several places, namely around delayed ref processing Core: - more page to folio conversions: - relocation - send - compression - inline extent handling - super block write and wait - extent_map structure optimizations: - reduced structure size - code simplifications - add shrinker for allocated objects, the numbers can go high and could exhaust memory on smaller systems (reported) as they may not get an opportunity to be freed fast enough - extent locking optimizations: - reduce locking ranges where it does not seem to be necessary and are safe due to other means of synchronization - potential improvements due to lower contention, allocation/freeing and state management operations of extent state tracking structures - delayed ref cleanups and simplifications - updated trace points - improved error handling, warnings and assertions - cleanups and refactoring, unification of error handling paths" * tag 'for-6.10-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux: (122 commits) btrfs: qgroup: fix initialization of auto inherit array btrfs: count super block write errors in device instead of tracking folio error state btrfs: use the folio iterator in btrfs_end_super_write() btrfs: convert super block writes to folio in write_dev_supers() btrfs: convert super block writes to folio in wait_dev_supers() bio: Export bio_add_folio_nofail to modules btrfs: remove duplicate included header from fs.h btrfs: add a cached state to extent_clear_unlock_delalloc btrfs: push extent lock down in submit_one_async_extent btrfs: push lock_extent down in cow_file_range() btrfs: move can_cow_file_range_inline() outside of the extent lock btrfs: push lock_extent into cow_file_range_inline btrfs: push extent lock into cow_file_range btrfs: push extent lock into run_delalloc_cow btrfs: remove unlock_extent from run_delalloc_compressed btrfs: push extent lock down in run_delalloc_nocow btrfs: adjust while loop condition in run_delalloc_nocow btrfs: push extent lock into run_delalloc_nocow btrfs: push the extent lock into btrfs_run_delalloc_range btrfs: lock extent when doing inline extent in compression ...
