I don't think so. It's relying on nmi_enter() also makes in_interrupt() return true. Like I said before. An NMI interrupting userspace should be no different than an interrupt interrupting userspace. They both can trigger vmalloc faults, and we should be able to deal with it. -- Steve -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
