Merge tag 'f2fs-for-6.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs

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"
