Seems to me that if you don't have load balancing turned off, you can't be very concerned about perturbation, so this should be tied into the load balancing on/off switch as an extension to isolating cores from the #1 perturbation source, the scheduler. I also didn't notice a check for is_cpu_exclusive() at a glance, which would be a bug, but one that would go away if this additional isolation were coupled to the existing isolation switch. -Mike -- To unsubscribe from this list: send the line "unsubscribe cgroups" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
