The pending_packet_queue is only accessed from within drivers/ieee1394/ieee1394_core.c, and only via net/core/skbuff.c's access functions for queueing/ dequeueing/ queuewalking. Or am I missing something?

Quick grep show following two irq handlers as examples:

ohci_irq_handler() | lynx_irq_handler()
  hpsb_bus_reset()
    abort_requests()
      skb_dequeue()
        spin_lock_irqsave()
That spin_lock is called directly from within irq handler.

Yes, definitely. What I wanted to reassure myself about was rather that no other net/ code besides skbuff.c's touches this queue. IOW only the ieee1394 low and mid layer control the contexts within which the queue lock is used.
