 "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.

  There is also a new mount option, compress_mode=fs|user, which can

  Chao also added a checksum feature with a mount option so that

  Summary:

  Enhancements:
   - 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 fixes:
   - 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: fix race of pending_pages in decompression 2020-12-08T23:39:14+00:00 Daeho Jeong daehojeong@google.com 2020-12-05T04:26:26+00:00 6422a71ef40e4751d59b8c9412e7e2dafe085878 I found out f2fs_free_dic() is invoked in a wrong timing, but f2fs_verify_bio() still needed the dic info and it triggered the below kernel panic. It has been caused by the race condition of pending_pages value between decompression and verity logic, when the same compression cluster had been split in different bios. By split bios, f2fs_verify_bio() ended up with decreasing pending_pages value before it is reset to nr_cpages by f2fs_decompress_pages() and caused the kernel panic.
