Some app may have different cgroup settings in cpuset and schedtune for its threads, so let blkio follow cpuset only, which represents the app's current state more accurately. Otherwise, if that thread is doing IO, then its performance will be affected because its blkio group is in lower priority group as schedtune. ex: an app is now in top-app, but some thread of it set schedtune group to background, and blkio follows schedtune because it is called later. Main thread: 6:schedtune:/top-app 5:memory:/ 4:cpuset:/top-app 3:cpuacct:/uid_1000/pid_8766 2:cpu:/ 1:blkio:/ 0::/ Some thread: 6:schedtune:/background 5:memory:/ 4:cpuset:/top-app 3:cpuacct:/uid_1000/pid_8766 2:cpu:/ 1:blkio:/background 0::/ Bug: 124727032 Test: blkio has same settings with cpuset Change-Id: I9a140c7d9d93e1dd43c34c8cf066f4a62e2bf604 |
