It could probably be refactored.  That being said, I suspect we're
better off deferring the whole iov_iter direction cleanup. It's a bit
ugly right now, but there is nothing urgent.  The gup pin work otoh
really is something we need to get down rather sooner than later.

So what about deferring this whole cleanup for now?
