Because there's a number of things wanting sched_clock() and the likes to be synchronized across cpus, its impossible to make _unstolen() synchronized because different vcpus can get different service levels. Also, I think you want to keep measuring scheduling latency and other such things in actual wall-time. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
