This patch has been tested with xfstests by running 'kvm-xfstests -c
f2fs -g auto' with and without this patch; no regressions were seen.

Some tests fail both before and after, and the test results are:
f2fs/default: 683 tests, 9 failures, 226 skipped, 30297 seconds

Can you please take a look at gerneic/473 ?

Other concern is, it needs to test this implementation on compressed file,
since the logic is a little bit complicated.
