It also will crash if an event is delivered before\nthe srq object is finished initializing.\n\nUse the spinlock since it isn't easy to make RCU work, use\nrefcount_inc_not_zero() to protect against partially initialized objects,\nand order the refcount_set() to be after the srq is fully initialized.",
