Merge tag 'f2fs-for-6.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs

Pull f2fs updates from Jaegeuk Kim:
 "A pretty small update including mostly minor bug fixes in zoned
  storage along with the large section support.

  Enhancements:
   - add support for FS_IOC_GETFSSYSFSPATH
   - enable atgc dynamically if conditions are met
   - use new ioprio Macro to get ckpt thread ioprio level
   - remove unreachable lazytime mount option parsing

  Bug fixes:
   - fix null reference error when checking end of zone
   - fix start segno of large section
   - fix to cover read extent cache access with lock
   - don't dirty inode for readonly filesystem
   - allocate a new section if curseg is not the first seg in its zone
   - only fragment segment in the same section
   - truncate preallocated blocks in f2fs_file_open()
   - fix to avoid use SSR allocate when do defragment
   - fix to force buffered IO on inline_data inode

  And some minor code clean-ups and sanity checks"
