I'm no longer sure that this does affect your latency anymore. It probably does indirectly somehow. I still think it has to do with the bitspinlocks. But I'm not sure. Just let me know if you want to be taken off this thread and I'll remove you from my CC list. Until then, I'll keep you on. -- Steve - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
