yes. Do you mean that we should anticipate and rename utilization_load_avg into utilization_runnable_avg to make space for a utilization_blocked_avg that could be added in future ?
nah, just trying to put things straight in my brain, including what is 'missing'.
As Ben pointed out in the scale-invariance thread, we need blocked utilization. I fully agree with that. It doesn't make any sense not to include it. In fact I do have the patch already.
If you want to rename utlization_load_avg you should name it utilization_running_avg, not utilization_runnable_avg :) Or even better, something shorter.
