Chris Wilson 8e87e0139a drm/i915/gt: Mark timeline->cacheline as destroyed after rcu grace period 
Since we take advantage of RCU for some i915_active objects, like the
intel_timeline_cacheline, we need to delay the i915_active_fini until
after the RCU grace period and we perform the kfree -- that is until
after all RCU protected readers.
