Oh, okay, this part of thread was for request based dm, so I assumed
you were talking about it.

If you look at the two patches for bio-based ones.  The first one is
basically what you're talking about w/ s/barrier/flush/ renames and
dropping of -EOPNOTSUPP.  It doesn't really change the mechanism much.
If you don't feel comfortable about the second one, we sure can
postpone it but it's still quite away from the next merge window and
what would be the point of delaying it?

Thanks.
