A highlight perhaps is the parallel fsync performance improvements, numbers below. Regarding the dio/iomap that was reverted last time, the required API changes are likely to land in the upcoming cycle, the btrfs part will be updated afterwards. User visible changes: - new mount option rescue= to group all recovery-related mount options so we don't have many specific options, currently introducing only aliases for existing options, future extensions are in development to allow read-only mount with partially damaged structures: - usebackuproot is an alias for rescue=usebackuproot - nologreplay is an alias for rescue=nologreplay - start deprecation of mount option inode_cache, removal scheduled to v5.11 - removed deprecated mount options alloc_start and subvolrootid - device stats corruption counter gets incremented when a checksum mismatch is found - qgroup information exported in /sys/fs/btrfs/<UUID>/qgroups/<id> using sysfs - add link /sys/fs/btrfs/<UUID>/bdi pointing to the associated backing dev info - FS_INFO ioctl enhancements: - add flags to request/describe newly added items - new item: numeric checksum type and checksum size - new item: generation - new item: metadata_uuid - seed device: with one new read-write device added, print the new device information in /proc/mounts - balance: detect cancellation by Ctrl-C in existing cancellation points Performance improvements: - optimized versions of various helpers on little-endian architectures, where we don't have to do LE/BE conversion from on-disk format - tree-log/fsync optimizations leading to lower max latency reported by dbench, reduced by about 12% - all chunk tree leaves are prefetched at mount time, can improve mount time on large (terabyte-sized) filesystems - speed up parallel fsync of files with reflinked/deduped extents, with jobs 16 to 1024 the throughput gets improved roughly by 50% on average and runtime decreased roughly by 30% on average, notable outlier is 128 jobs with +121.2% on throughput and -54.6% runtime - another speed up of parallel fsync, reduce number of checksum tree lookups and contention, the improvements start to show up with 2 tasks with +20% throughput and -16% runtime up to 64 with +200% throughput and -66% runtime Core: - umount-time qgroup leak checker - qgroups - add a way to unreserve partial range after failure, avoiding some EDQUOT errors - improved flushing logic when EDQUOT is hit - possible EINTR interruption caused by failed reservations after transaction start is better handled and documented - transaction abort errors are unified to EROFS in case it's not the original reason of abort or we don't have other way to determine the reason Fixes: - make truncate succeed on a NOCOW file even if data space is exhausted - fix cancelling balance on filesystem with exhausted metadata space - anon block device: - preallocate anon bdev when subvolume is created to report failure early - shorten time the anon bdev id is allocated - don't allocate anon bdev for internal roots - minor memory leak in ref-verify - refuse invalid combinations of compression and NOCOW file flags - lockdep fixes, updating the device locks - remove obsolete fallback logic for block group profile adjustments when switching from 1 to more devices, causing allocation of unwanted block groups Other cleanups, refactoring, simplifications: - conversions from struct inode to struct btrfs_inode in internal functions - removal of unused struct members" * tag 'for-5.9-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux: (151 commits) btrfs: do not set the full sync flag on the inode during page release btrfs: release old extent maps during page release btrfs: fix race between page release and a fast fsync btrfs: open-code remount flag setting in btrfs_remount btrfs: if we're restriping, use the target restripe profile btrfs: don't adjust bg flags and use default allocation profiles btrfs: fix lockdep splat from btrfs_dump_space_info btrfs: move the chunk_mutex in btrfs_read_chunk_tree btrfs: open device without device_list_mutex btrfs: sysfs: use NOFS for device creation btrfs: return EROFS for BTRFS_FS_STATE_ERROR cases btrfs: document special case error codes for fs errors btrfs: don't WARN if we abort a transaction with EROFS btrfs: reduce contention on log trees when logging checksums btrfs: remove done label in writepage_delalloc btrfs: add comments for btrfs_reserve_flush_enum btrfs: relocation: review the call sites which can be interrupted by signal btrfs: avoid possible signal interruption of btrfs_drop_snapshot() on relocation tree btrfs: relocation: allow signal to cancel balance btrfs: raid56: remove out label in __raid56_parity_recover ... |
