So a problem with such an interfaces is that is makes it far too easy to generate completely broken domains. You can, for two cpus in the same domain provide, different flags; such a configuration doesn't make any sense at all. Now I see why people would like to have this; but unless we can make it robust I'd be very hesitant to go this route. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
