Chris Wilson 7d622351c9 drm/i915/fence: Use rcu to defer freeing of irq_work ... It is illegal to perform an immediate free of the struct irq_work from inside the irq_work callback (as irq_work_run_list modifies work->flags after execution of the work->func()). As we use the irq_work to coordinate the freeing of the callback from two different softirq paths, we need to defer the kfree from inside our irq_work callback, for which we can use kfree_rcu.
