    Pull f2fs updates from Jaegeuk Kim:
     "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.
    
      Enhancements:
       - 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 fixes:
       - 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"
