Take a look at D77005. Shilei introduced some real askync versions for a
different reason already. You can build on top of that patch and extend
it if needed further.

Interesting. I'll need to see small examples. For now, focus on the
simple case, we'll get to the rest later. However, we should really
start by creating test cases that show the initial code and FIXMEs that
describe how we want it to look like.

We want to eventually split all transfers into two but let's start with
a single one.

We split, then we move them apart. The cannot be moved over instructions
that might change behavior if we move them, e.g. an aliasing memory
operation or a kernel call that uses the data.

I do not have one. I thought they might or they have an FAQ that
describes what to do. I know they have some required things, so check
their webpage. I think you have to use google docs, I might be wrong.
Your categories look good, make the deliverables not too specific but
describe more ideas to work on. We'll make tasks as we go as you are not
the only one working on this general area.
Feel free to send me a draft of the proposal for feedback.
Cheers,
Johannes
