Merge tag 'f2fs-for-6.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs

Pull f2fs update from Jaegeuk Kim:
 "In this series, we've some progress to support Zoned block device
  regarding to the power-cut recovery flow and enabling
  checkpoint=disable feature which is essential for Android OTA.

  Other than that, some patches touched sysfs entries and tracepoints
  which are minor, while several bug fixes on error handlers and
  compression flows are good to improve the overall stability.

  Enhancements:
   - enable checkpoint=disable for zoned block device
   - sysfs entries such as discard status, discard_io_aware, dir_level
   - tracepoints such as f2fs_vm_page_mkwrite(), f2fs_rename(),
     f2fs_new_inode()
   - use shared inode lock during f2fs_fiemap() and f2fs_seek_block()

  Bug fixes:
   - address some power-cut recovery issues on zoned block device
   - handle errors and logics on do_garbage_collect(),
     f2fs_reserve_new_block(), f2fs_move_file_range(),
     f2fs_recover_xattr_data()
   - don't set FI_PREALLOCATED_ALL for partial write
   - fix to update iostat correctly in f2fs_filemap_fault()
   - fix to wait on block writeback for post_read case
   - fix to tag gcing flag on page during block migration
   - restrict max filesize for 16K f2fs
   - fix to avoid dirent corruption
   - explicitly null-terminate the xattr list

  There are also several clean-up patches to remove dead codes and
  better readability"
