Is there a specific problem you bumped into which you are fixing with
this approach? Can you please describe it?

I'm concerned that coupling the vring size with coherent memory
allocated by rpmsg may not be safe. It'd also be an implicit side
effect that may surprise users, so let's consider our alternatives.

Thanks,
