Linus Torvalds a641a88e5d f2fs-for-5.3-rc1
In this round, we've introduced native swap file support which can exploit DIO,
 enhanced existing checkpoint=disable feature with additional mount option to
 tune the triggering condition, and allowed user to preallocate physical blocks
 in a pinned file which will be useful to avoid f2fs fragmentation in append-only
 workloads. In addition, we've fixed subtle quota corruption issue.
 
 Enhancement:
  - add swap file support which uses DIO
  - allocate blocks for pinned file
  - allow SSR and mount option to enhance checkpoint=disable
  - enhance IPU IOs
  - add more sanity checks such as memory boundary access
 
 Bug fix:
  - quota corruption in very corner case of error-injected SPO case
  - fix root_reserved on remount and some wrong counts
  - add missing fsck flag
 
 Some patches were also introduced to clean up ambiguous i_flags and debugging
 messages codes.
