[Intel-gfx] [PATCH 8/9] drm/i915: clean-up i915_gem_flush_gpu_write_domain

[Daniel Vetter]

Now that we have an exact gpu write domain tracking, we don't need
to move objects to the active list ourself. i915_add_request will
take care of that under all circumstances.

Idea stolen from a patch by Chris Wilson <chris at chris-wilson.co.uk>.
