Pull f2fs updates from Jaegeuk Kim:
 "In this cycle, we mainly fixed some corner cases that manipulate a
  per-file compression flag inappropriately. And, we found f2fs counted
  valid blocks in a section incorrectly when zone capacity is set, and
  thus, fixed it with additional sysfs entry to check it easily.

  Lastly, this series includes several patches with respect to the new
  atomic write support such as a couple of bug fixes and re-adding
  atomic_write_abort support that we removed by mistake in the previous
  release.

  Enhancements:
   - add sysfs entries to understand atomic write operations and zone
     capacity
   - introduce memory mode to get a hint for low-memory devices
   - adjust the waiting time of foreground GC
   - decompress clusters under softirq to avoid non-deterministic
     latency
   - do not skip updating inode when retrying to flush node page
   - enforce single zone capacity

  Bug fixes:
   - set the compression/no-compression flags correctly
   - revive F2FS_IOC_ABORT_VOLATILE_WRITE
   - check inline_data during compressed inode conversion
   - understand zone capacity when calculating valid block count

  As usual, the series includes several minor clean-ups and sanity
  checks"
