    Linus Torvalds authored
    Pull f2fs updates from Jaegeuk Kim:
     "In this round, we've focused on bug fixes since Pixel devices have
      been shipping with f2fs. Some of them were related to hardware
      encryption support which are actually not an issue in mainline, but
      would be better to merge them in order to avoid potential bugs.
    
      Enhancements:
       - do GC sub-sections when the section is large
       - add a flag in ioctl(SHUTDOWN) to trigger fsck for QA
       - use kvmalloc() in order to give another chance to avoid ENOMEM
    
      Bug fixes:
       - fix accessing memory boundaries in a malformed iamge
       - GC gives stale unencrypted block
       - GC counts in large sections
       - detect idle time more precisely
       - block allocation of DIO writes
       - race conditions between write_begin and write_checkpoint
       - allow GCs for node segments via ioctl()
    
      There are various clean-ups and minor bug fixes as well"
