#     Merge tag 'f2fs-for-5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs
#     
#     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"
