Josep asked me if we are going to push this for 1.10. @Sree, what do you thing? 
IMO if we push this, we also should merge Julien's work for dmabuf to
downstream.

In the case if dmabuf to upstream, I don't see more room for improvement
(perhaps I'm missing something), but disabling the linear storage flag in the
allocator creation.
