  f2fs: improve print log in f2fs_sanity_check_ckpt() (2019-07-10 18:44:47 -0700)

----------------------------------------------------------------
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.
