I'm not sure I agree with that statement. Its a transition thing and therefore statistically irrelevant on the whole -- assuming we transition rarely. And for those who cannot deal with the transition effects, a barrier was proposed which would wait until the system hit this state -- although the specific implementation of this isn't clear yet afaik. I very much think we should focus on getting adaptive tick working as simple as possible and worry about transition effects later, if at all. -- 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/
