It is indeed hard to follow, and maybe I missed something, but from
what I can tell, your series looks all sane. It certainly seems to
make things much more straightforward.

Of course, exactly _because_ it's such a messy area, maybe it
introduces something odd, but all the patches look relatively
straightforward. And you remove more lines of code than you add, which
is always nice to see.

So ack from me.

Oleg? Jann? Anybody? Do you see anything strange that I missed?
