I'm not quite sure why that is, but I kinda like that, the policy implementation should never export stuff. Code outside the scheduler cannot ever know the policy of a task, hence policy specific exports are bad. A generic export with policy implementations (like the sched_class::yield_to() proposal) are the proper way. -- 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
