Merge tag 'f2fs-for-6.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fsHEADmaster
Pull f2fs updates from Jaegeuk Kim: "This series focuses on minor clean-ups and performance optimizations across sysfs, documentation, debugfs, tracepoints, slab allocation, and GC. Furthermore, it resolves several corner-case bugs caught by xfstests, as well as issues related to 16KB page support and f2fs_enable_checkpoint. Enhancement: - wrap ASCII tables in literal blocks to fix LaTeX build - optimize trace_f2fs_write_checkpoint with enums - support to show curseg.next_blkoff in debugfs - add a sysfs entry to show max open zones - add fadvise tracepoint - use global inline_xattr_slab instead of per-sb slab cache - set default valid_thresh_ratio to 80 for zoned devices - maintain one time GC mode is enabled during whole zoned GC cycle Bug fix: - ensure node page reads complete before f2fs_put_super() finishes - do not account invalid blocks in get_left_section_blocks() - revert summary entry count from 2048 to 512 in 16kb block support - detect recoverable inode during dryrun of find_fsync_dnodes() - fix age extent cache insertion skip on counter overflow - add sanity checks before unlinking and loading inodes - ensure minimum trim granularity accounts for all devices - block cache/dio write during f2fs_enable_checkpoint() - propagate error from f2fs_enable_checkpoint() - invalidate dentry cache on failed whiteout creation - avoid updating compression context during writeback - avoid updating zero-sized extent in extent cache - avoid potential deadlock" * tag 'f2fs-for-6.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs: (39 commits) f2fs: ignore discard return value f2fs: optimize trace_f2fs_write_checkpoint with enums f2fs: fix to not account invalid blocks in get_left_section_blocks() f2fs: support to show curseg.next_blkoff in debugfs docs: f2fs: wrap ASCII tables in literal blocks to fix LaTeX build f2fs: expand scalability of f2fs mount option f2fs: change default schedule timeout value f2fs: introduce f2fs_schedule_timeout() f2fs: use memalloc_retry_wait() as much as possible f2fs: add a sysfs entry to show max open zones f2fs: wrap all unusable_blocks_per_sec code in CONFIG_BLK_DEV_ZONED f2fs: simplify list initialization in f2fs_recover_fsync_data() f2fs: revert summary entry count from 2048 to 512 in 16kb block support f2fs: fix to detect recoverable inode during dryrun of find_fsync_dnodes() f2fs: fix return value of f2fs_recover_fsync_data() f2fs: add fadvise tracepoint f2fs: fix age extent cache insertion skip on counter overflow f2fs: Add sanity checks before unlinking and loading inodes f2fs: Rename f2fs_unlink exit label f2fs: ensure minimum trim granularity accounts for all devices ...
