> When updating avg_idle, if the delta exceeds some max value, then avg_idle > gets set to the max, regardless of what the previous avg was. This can cause > avg_idle to often be overestimated. > > This patch modifies the way we update avg_idle by always updating it with the > function call to update_avg() first. Then, if avg_idle exceeds the max, we set > it to the max. > > Signed-off-by: Jason Low <jason.low2@hp.com> > Reviewed-by: Rik van Riel <riel@redhat.com>
