What is _rd and _wt supposed to stand for? And speaking more generally, could you write up some more detailed notes about all of the various new functions they have been added, when they should be used, and some kind of roadmap about how things are supposed to work beyond the very high-level description in the introduction in your patch series? Ideally it would go into the Documentation directory, so that after this patch set gets applied, people will be able to refer to it to understand how things are supposed to work.
