Merge tag 'f2fs-for-6.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk...

Pull f2fs updates from Jaegeuk Kim:
 "In this round, we've got a huge number of patches that improve code
  readability along with minor bug fixes, while we've mainly fixed some
  critical issues in recently-added per-block age-based extent_cache,
  atomic write support, and some folio cases.

  Enhancements:

   - add sysfs nodes to set last_age_weight and manage
     discard_io_aware_gran

   - show ipu policy in debugfs

   - reduce stack memory cost by using bitfield in struct f2fs_io_info

   - introduce trace_f2fs_replace_atomic_write_block

   - enhance iostat support and adds flush commands

  Bug fixes:

   - revert "f2fs: truncate blocks in batch in __complete_revoke_list()"

   - fix kernel crash on the atomic write abort flow

   - call clear_page_private_reference in .{release,invalid}_folio

   - support .migrate_folio for compressed inode

   - fix cgroup writeback accounting with fs-layer encryption

   - retry to update the inode page given data corruption

   - fix kernel crash due to NULL io->bio

   - fix some bugs in per-block age-based extent_cache:
       - wrong calculation of block age
       - update age extent in f2fs_do_zero_range()
       - update age extent correctly during truncation"
