[PATCH RESEND] perf/core: Fix installing cgroup event into cpu

2018-01-22 Thread linxiulei
From: "leilei.lin" Do not install cgroup event into the CPU context if the cgroup is not running on this CPU While there is no task of cgroup running specified CPU, current kernel still install cgroup event into CPU context, that causes another cgroup event can't be installed into this CPU. Sig
