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"
