it looks like I'm a step further understanding the problems which come
with this change.
I've more or less audited all use cases and think that only i915 is left
with the following lock inversion:

Now my question is what is &obj->mm.lock used for and why do you guys
call dma_buf_map_attachment() while holding it?
Thanks in advance,
