Our recent test shows that the idle value of /proc/stat can decrease. Is this an unreported bug? or it has been reported and the solution is waiting to get merged. The results of the two readings from /proc/stat are shown as below, the interval between the two readings is 150 ms: cat /proc/stat cpu0 5536 10 14160 4118960 0 0 227128 0 0 0 cat /proc/stat cpu0 5536 10 14160 4118959 0 0 227143 0 0 0
