It's not so much that the mutex is more efficient. It's just that mutexes allow interrupt processing on that CPU while they are held, unlike spinlocks. So the use of spinlocks can increase the latency to service an interrupt request. We'd like to keep that latency as low as possible. - Paul -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
