Subject[PATCH v2 3/5] cgroup: Fix 'usage_usec' time in root's cpu.stat
Date
Global CPUTIME_USER counter already includes CPUTIME_GUEST
Also CPUTIME_NICE already includes CPUTIME_GUEST_NICE.

Remove additions of CPUTIME_GUEST[_NICE] to total ->sum_exec_runtime
to not account them twice.

Fixes: 936f2a70f207 ("cgroup: add cpu.stat file to root cgroup")
