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.
