Above invoking is added in commit ("f2fs: readahead cp payload pages
when mount") at ~9/12/2015, but sadly it's complete wrong due to my fault,
so it is removed in our dev-test branch by Jaegeuk at ~9/26/2015. I can't
remember the time when this commit is removed from dev branch which is for
-next branch. I have checked next-20151022, this commit is gone, I think
the last -next will not make any trouble to you. Could you check that?

When this commit was updated in Jaegeuk's tree, above invoking in
fs/f2fs/checkpoint.c:707 was gone.

Thanks,
