    Merge tag 'for-f2fs-4.6' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs
    
    Pull f2fs updates from Jaegeuk Kim:
     "New Features:
       - uplift filesystem encryption into fs/crypto/
       - give sysfs entries to control memroy consumption
    
      Enhancements:
       - aio performance by preallocating blocks in ->write_iter
       - use writepages lock for only WB_SYNC_ALL
       - avoid redundant inline_data conversion
       - enhance forground GC
       - use wait_for_stable_page as possible
       - speed up SEEK_DATA and fiiemap
    
      Bug Fixes:
       - corner case in terms of -ENOSPC for inline_data
       - hung task caused by long latency in shrinker
       - corruption between atomic write and f2fs_trace_pid
       - avoid garbage lengths in dentries
       - revoke atomicly written pages if an error occurs
    
      In addition, there are various minor bug fixes and clean-ups"
