Linus Torvalds ff49c86f27 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.
