If you make the scheduler take steal time into account like Jeremy proposed then you schedule on serviced time and the steal time gain is proportional to the existing service distribution. Still, then you know, then what are you going to do about it? Are you going to avoid the hypervisor from scheduling when that one task is running? What good is knowing something you cannot do anything about. -- To unsubscribe from this list: send the line "unsubscribe linux-s390" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
