    Pull f2fs updates from Jaegeuk Kim:
     "In this series, we've implemented transparent compression
      experimentally. It supports LZO and LZ4, but will add more later as we
      investigate in the field more.
    
      At this point, the feature doesn't expose compressed space to user
      directly in order to guarantee potential data updates later to the
      space. Instead, the main goal is to reduce data writes to flash disk
      as much as possible, resulting in extending disk life time as well as
      relaxing IO congestion.
    
      Alternatively, we're also considering to add ioctl() to reclaim
      compressed space and show it to user after putting the immutable bit.
    
      Enhancements:
       - add compression support
       - avoid unnecessary locks in quota ops
       - harden power-cut scenario for zoned block devices
       - use private bio_set to avoid IO congestion
       - replace GC mutex with rwsem to serialize callers
    
      Bug fixes:
       - fix dentry consistency and memory corruption in rename()'s error case
       - fix wrong swap extent reports
       - fix casefolding bugs
       - change lock coverage to avoid deadlock
       - avoid GFP_KERNEL under f2fs_lock_op
    
      And, we've cleaned up sysfs entries to prepare no debugfs"
