f2fs-for-5.11-rc1
f2fs-for-5.11-rc1 In this round, we've made more work into per-file compression support. For example, F2FS_IOC_GET|SET_COMPRESS_OPTION provides a way to change the algorithm or cluster size per file. F2FS_IOC_COMPRESS|DECOMPRESS_FILE provides a way to compress and decompress the existing normal files manually along with a new mount option, compress_mode=fs|user, which can control who compresses the data. Chao also added a checksum feature with a mount option so that we are able to detect any corrupted cluster. In addition, Daniel contributed casefolding with encryption patch, which will be used for Android devices. Enhancement: - add ioctls and mount option to manage per-file compression feature - support casefolding with encryption - support checksum for compressed cluster - avoid IO starvation by replacing mutex with rwsem - add sysfs, max_io_bytes, to control max bio size Bug fix: - fix use-after-free issue when compression and fsverity are enabled - fix consistency corruption during fault injection test - fix data offset for lseek - get rid of buffer_head which has 32bits limit in fiemap - fix some bugs in multi-partitions support - fix nat entry count calculation in shrinker - fix some stat information And, we've refactored some logics and fix minor bugs as well.

f2fs-for-5.10-rc1
f2fs-for-5.10-rc1 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. Enhancement: - 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 fix: - 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.
