In this example using rq->avg leads to imbalance whereas unweighted load
would not. Correct me if I missed anything.
You just miss to take into account how the imbalance is computed
I don't think so. I'm aware that the imbalance is calculated based on
the runnable_load_avg of the cpus. But if you pick the wrong cpus to
compare to begin with, it doesn't matter.
