The way that is worded, that wouldn't sound like CONFIG_EXPERIMENTAL even if that worked the way we wanted. Just a clearly worded separate config option for your feature would be best in that case. Yes there are tons of options to wade through, but you can't make CONFIG_EXPERIMENTAL a binary for what you describe, since the experimental options i'd want (user namespaces, etc) would not be the same ones you'd want. -serge -- 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/
