--- Comment #16 from Nicolas Dufresne (stormer) <nicolas at ndufresne.ca> ---
Looking again, the allocator checks for dmabuf importation, but not for expbuf,
sorry. I'm thinking about just using your patch as-is in fact, I was nitpicking
something that didn't exist.

I'll merge into my local tree to see how it behaves. I already know it breaks
if you combined dmabuf and tee with various sink. The sink will store a cached
dmabuf wrapper as a memory quark. As the quark name is the same regardless of
the tee branch, we end up with one branch getting their object destroyed when
the other try to cache.
