I'm *sure* you meant to document that somewhat non-trivial proposed new kernel API as soon as you got a moment. But, since I went to the trouble of reverse engineering it, I decided not to wait and to make a little unreliable guide of my own. For those who are curious about how vringfd() is meant to work (or about how badly I misunderstood it), the info is at:

Hopefully it will be helpful,
