Merge tag 'f2fs-for-5.3' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs 

Pull f2fs updates from Jaegeuk Kim:
 "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.

  Enhancements:
   - 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 fixes:
   - 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"

checkpoint=%s[:%u[%]] Set to "disable" to turn off checkpointing. Set to "enable"
to reenable checkpointing. Is enabled by default. While
disabled, any unmounting or unexpected shutdowns will cause
the filesystem contents to appear as they did when the
filesystem was mounted with that option.
While mounting with checkpoint=disabled, the filesystem must
run garbage collection to ensure that all available space can
be used. If this takes too much time, the mount may return
EAGAIN. You may optionally add a value to indicate how much
of the disk you would be willing to temporarily give up to
avoid additional garbage collection. This can be given as a
number of blocks, or as a percent. For instance, mounting
with checkpoint=disable:100% would always succeed, but it may
hide up to all remaining free space. The actual space that
would be unusable can be viewed at /sys/fs/f2fs/<disk>/unusable
This space is reclaimed once checkpoint=enable.

Fallocate(2) Policy
-------------------
The default policy follows the below posix rule.
Allocating disk space
The default operation (i.e., mode is zero) of fallocate() allocates
the disk space within the range specified by offset and len. The
file size (as reported by stat(2)) will be changed if offset+len is
greater than the file size. Any subregion within the range specified
by offset and len that did not contain data before the call will be
initialized to zero. This default behavior closely resembles the
behavior of the posix_fallocate(3) library function, and is intended
as a method of optimally implementing that function.
However, once F2FS receives ioctl(fd, F2FS_IOC_SET_PIN_FILE) in prior to
fallocate(fd, DEFAULT_MODE), it allocates on-disk blocks addressess having
zero or random data, which is useful to the below scenario where:
1. create(fd)
2. ioctl(fd, F2FS_IOC_SET_PIN_FILE)
3. fallocate(fd, 0, 0, size)
4. address = fibmap(fd, offset)
5. open(blkdev)
6. write(blkdev, address)
