One more observation: access to aggregate()->rq_weight etc arent correctly synchronized i.e while a cpu is doing a aggregate_walk_tree() in a domain, and thus possibly modifying rq_weight, load etc, other cpus could be concurrently accessing the same data. As a result, its possible to see inconsistent rq_weight, load, task_weight combination?
