First of all, I really appreciate that you tried this. Every open-coded
page walk has a set of common pitfalls, but is pretty unbounded in what
kinds of bugs it can contain. I think this at least gets us to the
point where some of those pitfalls won't happen. That's cool, but I'm a
worried that it hasn't gotten easier in the end.

Linus also had some strong opinions in the past on how page walks should
be written. He needs to have a look before we go much further.
