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" * tag 'for-6.9-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux: (114 commits) btrfs: reuse cloned extent buffer during fiemap to avoid re-allocations btrfs: fix race when detecting delalloc ranges during fiemap btrfs: fix off-by-one chunk length calculation at contains_pending_extent() btrfs: qgroup: allow quick inherit if snapshot is created and added to the same parent btrfs: qgroup: validate btrfs_qgroup_inherit parameter btrfs: include device major and minor numbers in the device scan notice btrfs: mark btrfs_put_caching_control() static btrfs: remove SLAB_MEM_SPREAD flag use btrfs: qgroup: always free reserved space for extent records btrfs: tree-checker: dump the page status if hit something wrong btrfs: compression: remove dead comments in btrfs_compress_heuristic() btrfs: subpage: make writer lock utilize bitmap btrfs: subpage: make reader lock utilize bitmap btrfs: unexport btrfs_subpage_start_writer() and btrfs_subpage_end_and_test_writer() btrfs: pass a valid extent map cache pointer to __get_extent_map() btrfs: merge btrfs_del_delalloc_inode() helpers btrfs: pass btrfs_device to btrfs_scratch_superblocks() btrfs: handle transaction commit errors in flush_reservations() btrfs: use KMEM_CACHE() to create btrfs_free_space cache btrfs: use KMEM_CACHE() to create delayed ref caches ...
