The changelog is missing the below CCs. :(
Since that's a new patch in this series, I expect some feedbacks and
thus I'll add them on the next respin.

The estimated utilization of a task is currently updated every time the
task is dequeued. However, to keep overheads under control, PELT signals
are effectively updated at maximum once every 1ms.
Thus, for really short running tasks, it can happen that their util_avg
value has not been updates
