Linus Torvalds 42612e7763 f2fs-for-5.8-rc1
In this round, we've added some knobs to enhance compression feature and harden
 testing environment. In addition, we've fixed several bugs reported from Android
 devices such as long discarding latency, device hanging during quota_sync, etc.
 
 Enhancement:
 - support lzo-rle algorithm
 - add two ioctls to release and reserve blocks for compression
 - support partial truncation/fiemap on compressed file
 - introduce sysfs entries to attach IO flags explicitly
 - add iostat trace point along with read io stat
 
 Bug fix:
 - fix long discard latency
 - flush quota data by f2fs_quota_sync correctly
 - fix to recover parent inode number for power-cut recovery
 - fix lz4/zstd output buffer budget
 - parse checkpoint mount option correctly
 - avoid inifinite loop to wait for flushing node/meta pages
 - manage discard space correctly
 
 And some refactoring and clean up patches were added.
