That's a pretty dangerously short name. :) How would this end up getting used? It seems like it would be dangerous to use once userspace was very far along. So would the kernel set it to 1 and then let (early??) userspace set it back to 0? That would let important userspace like /bin/init get mirrored memory without having to actually change much in userspace. This definitely needs some good documentation. Also, if it's insane to turn it back *on*, maybe it should be a one-way trip to turn off. -- 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/
