Merge tag 'for-6.9-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux
Pull btrfs updates from David Sterba:
"Mostly stabilization, refactoring and cleanup changes. There rest are
minor performance optimizations due to caching or lock contention
reduction and a few notable fixes.
Performance improvements:
- minor speedup in logging when repeatedly allocated structure is
preallocated only once, improves latency and decreases lock
contention
- minor throughput increase (+6%), reduced lock contention after
clearing delayed allocation bits, applies to several common
workload types
- skip full quota rescan if a new relation is added in the same
transaction
Fixes:
- zstd fix for inline compressed file in subpage mode, updated
version from the 6.8 time
- proper qgroup inheritance ioctl parameter validation
- more fiemap followup fixes after reduced locking done in 6.8:
- fix race when detecting delalloc ranges
Core changes:
- more debugging code:
- added assertions for a very rare crash in raid56 calculation
- tree-checker dumps page state to give more insights into
possible reference counting issues
- add checksum calculation offloading sysfs knob, for now enabled
under DEBUG only to determine a good heuristic for deciding the
offload or synchronous, depends on various factors (block group
profile, device speed) and is not as clear as initially thought
(checksum type)
- error handling improvements, added assertions
- more page to folio conversion (defrag, truncate), cached size and
shift
- preparation for more fine grained locking of sectors in subpage
mode
- cleanups and refactoring:
- include cleanups, forward declarations
- pointer-to-structure helpers
- redundant argument removals
- removed unused code
- slab cache updates, last use of SLAB_MEM_SPREAD removed"
