Chris Wilson d8af05ff38 drm/i915: Allow sharing the idle-barrier from other kernel requests ... By placing our idle-barriers in the i915_active fence tree, we expose those for reuse by other components that are issuing requests along the kernel_context. Reusing the proto-barrier active_node is perfectly fine as the new request implies a context-switch, and so an opportune point to run the idle-barrier. However, the proto-barrier is not equivalent to a normal active_node and care must be taken to avoid dereferencing the ERR_PTR used as its request marker. v2: Comment the more egregious cheek v3: A glossary!
