FYI, we noticed the below changes on
https://git.kernel.org/pub/scm/linux/kernel/git/mel/linux sched-disable-schedstats-v3r1
commit 0c9ceffc3460e0dd67dd0996bfe90d97771ff6a6 ("sched: Make schedstats a runtime tunable that is disabled by default v3")
Part of change may come from latencytop is disabled too.
