Glauber Costa 54c707e98d sched/accounting: Re-use scheduler statistics for the root cgroup ... Right now, after we collect tick statistics for user and system and store them in a well known location, we keep the same statistics again for cpuacct. Since cpuacct is hierarchical, the numbers for the root cgroup should be absolutely equal to the system-wide numbers. So it would be better to just use it: this patch changes cpuacct accounting in a way that the cpustat statistics are kept in a struct kernel_cpustat percpu array. In the root cgroup case, we just point it to the main array. The rest of the hierarchy walk can be totally disabled later with a static branch - but I am not doing it here.
