Merge tag 'f2fs-for-5.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs
Pull f2fs updates from Jaegeuk Kim:
"In this round, we've added new features such as zone capacity for ZNS
and a new GC policy, ATGC, along with in-memory segment management. In
addition, we could improve the decompression speed significantly by
changing virtual mapping method. Even though we've fixed lots of small
bugs in compression support, I feel that it becomes more stable so
that I could give it a try in production.
Enhancements:
- suport zone capacity in NVMe Zoned Namespace devices
- introduce in-memory current segment management
- add standart casefolding support
- support age threshold based garbage collection
- improve decompression speed by changing virtual mapping method
Bug fixes:
- fix condition checks in some ioctl() such as compression, move_range, etc
- fix 32/64bits support in data structures
- fix memory allocation in zstd decompress
- add some boundary checks to avoid kernel panic on corrupted image
- fix disallowing compression for non-empty file
- fix slab leakage of compressed block writes
In addition, it includes code refactoring for better readability and
minor bug fixes for compression and zoned device support"
