Merge tag 'f2fs-for-5.1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs

Browse Source 
Pull f2fs updates from Jaegeuk Kim:
 "We've continued mainly to fix bugs in this round, as f2fs has been
  shipped in more devices. Especially, we've focused on stabilizing
  checkpoint=disable feature, and provided some interfaces for QA.

  Enhancements:
   - expose FS_NOCOW_FL for pin_file
   - run discard jobs at unmount time with timeout
   - tune discarding thread to avoid idling which consumes power
   - some checking codes to address vulnerabilities
   - give random value to i_generation
   - shutdown with more flags for QA

  Bug fixes:
   - clean up stale objects when mount is failed along with
     checkpoint=disable
   - fix system being stuck due to wrong count by atomic writes
   - handle some corrupted disk cases
   - fix a deadlock in f2fs_read_inline_dir

  We've also added some minor build error fixes and clean-up patches"
