Including a diffstat would be nice.

I can take it through my Rust alloc tree, but I think it would probably be
better you take it through the mm tree, since I don't expect this to conflict
with anything else in my tree anyways.

The Rust changes gonna need some more discussion though.

No probs.

Great, I'll add a note-to-self that discussion is ongoing.

Awesome, thank you very much! The first patch is unlikely to need a change, the second one will be reworked as discussed with Danilo and the plan is that I post the new version tomorrow or on Friday.
