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"
