Merge tag 'f2fs-for-5.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeu...

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"
