Merge tag 'f2fs-for-6.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs

Pull f2fs updates from Jaegeuk Kim:
 "In this cycle, we introduce a bigger page size support by changing the
  internal f2fs's block size aligned to the page size. We also continue
  to improve zoned block device support regarding the power off
  recovery. As usual, there are some bug fixes regarding the error
  handling routines in compression and ioctl.

  Enhancements:
   - Support Block Size == Page Size
   - let f2fs_precache_extents() traverses in file range
   - stop iterating f2fs_map_block if hole exists
   - preload extent_cache for POSIX_FADV_WILLNEED
   - compress: fix to avoid fragment w/ OPU during f2fs_ioc_compress_file()

  Bug fixes:
   - do not return EFSCORRUPTED, but try to run online repair
   - finish previous checkpoints before returning from remount
   - fix error handling of __get_node_page and __f2fs_build_free_nids
   - clean up zones when not successfully unmounted
   - fix to initialize map.m_pblk in f2fs_precache_extents()
   - fix to drop meta_inode's page cache in f2fs_put_super()
   - set the default compress_level on ioctl
   - fix to avoid use-after-free on dic
   - fix to avoid redundant compress extension
   - do sanity check on cluster when CONFIG_F2FS_CHECK_FS is on
   - fix deadloop in f2fs_write_cache_pages()"
