note that there is something relevant to improve in the implementation, that is the per-cpu irq stack size should be bigger than 4k, we use 16k on x86-64, on x86 it should be 8k. Currently you're decreasing _both_ the normal kernel context and even the irq stack in some condition. There's no good reason to decrease the irq stack too, that's cheap, it's per-cpu. - 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/
