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.

Thanks!!
