Subject: [GIT PULL] Btrfs updates for 6.5
Date: Mon, 26 Jun 2023 20:14:42 +0200 [thread overview]
Message-ID: <cover.1687802358.git.dsterba@suse.com> (raw)
Hi,
there are mainly core changes, refactoring and optimizations.
Performance is improved in some areas, overall there may be a cumulative
improvement due to refactoring that removed lookups in the IO path or
simplified IO submission tracking.
No merge conflicts. Please pull, thanks.
Core:
- submit IO synchronously for fast checksums (crc32c and xxhash), remove
high priority worker kthread
- read extent buffer in one go, simplify IO tracking, bio submission and
locking
- remove additional tracking of redirtied extent buffers, originally
added for zoned mode but actually not needed
- track ordered extent pointer in bio to avoid rbtree lookups during IO
- scrub, use recovered data stripes as cache to avoid unnecessary read
- in zoned mode, optimize logical to physical mappings of extents
- remove PageError handling, not set by VFS nor writeback
- cleanups, refactoring, better structure packing
- lots of error handling improvements
- more assertions, lockdep annotations
- print assertion failure with the exact line where it happens
- tracepoint updates
- more debugging prints
Performance:
- speedup in fsync(), better tracking of inode logged status can avoid
transaction commit
- IO path structures track logical offsets in data structures and does
not need to look it up
User visible changes:
- don't commit transaction for every created subvolume, this can reduce
time when many subvolumes are created in a batch
- print affected files when relocation fails
- trigger orphan file cleanup during START_SYNC ioctl
Notable fixes:
- fix crash when disabling quota and relocation
- fix crashes when removing roots from drity list
- fix transacion abort during relocation when converting from newer
profiles not covered by fallback
- in zoned mode, stop reclaiming block groups if filesystem becomes
read-only
- fix rare race condition in tree mod log rewind that can miss some
btree node slots
- with enabled fsverity, drop up-to-date page bit in case the
verification fails
