Btw., I got this working with i915 by allowing GEM_OPEN/GEM_FLINK on

This comes from 'intel_region_alloc_for_handle', which is called in
'intel_process_dri2_buffer'.
I've just talked with Christopher James Halse Rogers, and he already
made patches that should solve that.
The patches to support driImage version 7 were posted recently on Mesa,
And his older patches (probably need rebasing):
https://github.com/RAOF/mesa/commit/cc797647eaa0e59929eca09ad1c5936cab74144b
https://github.com/RAOF/mesa/commit/1ff8df28f25f98b2e4a12f7fb3085b7d0adbfdf3

Combined with setting the name field to null (instead of generating a
name) and setting the fd field to a prime dma-buf when creating a buffer
(in get_back_bo),
it should avoid using names at all, and use dma-buf in Mesa, thus
enabling using render-nodes with Mesa.
