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"
