Actually, the initial patch which drops plugs is not mainlined as well.
So, at this time, I just want to revert it by this patch, since I recognized
that there might be whatever possible use-cases of plugs in another way someday.
So for now, I lost the reason to eliminate the plugs.

Moreover, since every filesystems use plugs, f2fs doesn't need to be an
exceptional case in terms of that (except hm-smr). So, let me sync f2fs
with other filesystems at this moment.

I totally agree that it'd be best to see their patches upstream, but I've
witnessed that it becomes a quite tough challenge to them.
