Hi Li or Tejun, f169007b2773f285e098cb84c74aac0154d65ff7 cgroup: fail if monitored file and event_control are in different cgroup This looks applicable to stable-3.4, that fixed the wrong usage notification, even the access to NULL pointer when monitored file and event_control are in different cgroup. It was built successful for me. What do you think? Thanks!
