Merge tag 'f2fs-for-5.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs

Pull f2fs updates from Jaegeuk Kim:
 "In this cycle, we've applied relatively small number of patches which
  fix subtle corner cases mainly, while introducing a new mount option
  to be able to fragment the disk intentionally for performance tests.

  Enhancements:

   - add a mount option to fragmente on-disk layout to understand the
     performance

   - support direct IO for multi-partitions

   - add a fault injection of dquot_initialize

  Bug fixes:

   - address some lockdep complaints

   - fix a deadlock issue with quota

   - fix a memory tuning condition

   - fix compression condition to improve the ratio

   - fix disabling compression on the non-empty compressed file

   - invalidate cached pages before IPU/DIO writes

  And, we've added some minor clean-ups as usual"
