One should not call blocking primitives inside a wait loop, since both require task_struct::state to sleep, so the inner will destroy the outer state. sigd_enq() will possibly sleep for alloc_skb(). Move sigd_enq() before prepare_to_wait() to avoid sleeping while waiting interruptibly. You do not actually need to call sigd_enq() after the initial prepare_to_wait() because we test the termination condition before calling schedule(). Based on suggestions from Peter Zijlstra.
