I am guessing you added this to try and speed up the fast path? It's overly restrictive for us since we do not need dmabuf necessarily. I spent a bit too much time wondering why things aren't working only to find this :(
So what else do you need? I was assured last round that nothing but dmabuf and potentially the huge page case (that really just is the page provider) would get added.
