Yeah, so that _should_ not trigger (obviously), and while I agree with the sentiment of sanity checks, I'm not sure its worth keeping that variable around just for that. Anyway, while I'm looking at struct tvec_base I notice the cpu member should be second after the lock, that'll save 8 bytes on the structure on 64bit machines. -- 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/
