  f2fs: compress: fix compression chksum (2020-12-10 09:13:53 -0800)

----------------------------------------------------------------
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.
