--- Comment #14 from Chris Wilson <chris at chris-wilson.co.uk> ---
I know where the memory starvation is coming from in v4.9+ -- it creates huge
objects and pwrites into just a page, and then never uses the object. We are
pinning the whole object, and since it is not used by the gpu, it is not
currently being accounted for -- a side-effect of the obj->mm.lock work. Even
with that fixed, this is going to be badly behaving.
