Chris Down	f98c25850f	cgroup v2: Don't require CPU controller for CPU accounting in 4.15+ ... systemd only uses functions that are as of Linux 4.15+ provided externally to the CPU controller (currently usage_usec), so if we have a new enough kernel, we don't need to set CGROUP_MASK_CPU for CPUAccounting=true as the CPU controller does not need to necessarily be enabled in this case. Part of this patch is modelled on an earlier patch by Ryutaroh Matsumoto (see PR #9665).	2018-11-18 12:21:41 +00:00
