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"
