      commit ffa770bd4b42925cb74886deb0fead959f4e52cf (HEAD -> drm-intel-next-queued, drm-intel/drm-intel-next-queued)
Author: Chris Wilson <chris@chris-wilson.co.uk>

    drm/i915/gem: Reduce context termination list iteration guard to RCU
    
    As we now protect the timeline list using RCU, we can drop the
    timeline->mutex for guarding the list iteration during context close, as
    we are searching for an inflight request. Any new request will see the
    context is banned and not be submitted. In doing so, pull the checks for
    a concurrent submission of the request (notably the
    i915_request_completed()) under the engine spinlock, to fully serialise
    with __i915_request_submit()). That is in the case of preempt-to-busy
    where the request may be completed during the __i915_request_submit(),
    we need to be careful that we sample the request status after
