Could we *always* fold the vmstat counters when entering idle mode? That would make the logic less complicated. There is nothing else to do since we are entering an idle state and if there are any counter deltas then we have the time to process them. This may also decrease the time that deltas exist significantly and an idle system will have accurate vmstat counters.
