Merge tag 'f2fs-for-6.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs
Pull f2fs updates from Jaegeuk Kim:
"This round looks fairly small comparing to the previous updates and
includes mostly minor bug fixes. Nevertheless, as we've still
interested in improving the stability, Chao added some debugging
methods to diagnoze subtle runtime inconsistency problem.
Enhancements:
- store all the corruption or failure reasons in superblock
- detect meta inode, summary info, and block address inconsistency
- increase the limit for reserve_root for low-end devices
- add the number of compressed IO in iostat
Bug fixes:
- DIO write fix for zoned devices
- do out-of-place writes for cold files
- fix some stat updates (FS_CP_DATA_IO, dirty page count)
- fix race condition on setting FI_NO_EXTENT flag
- fix data races when freezing super
- fix wrong continue condition check in GC
- do not allow ATGC for LFS mode
In addition, there're some code enhancement and clean-ups as usual"
