Hi. I think the tools/cgroup/cgroup_event_listener.c was useful in the past to demonstrate the non-traditional API of cgroup.event_control with FDs passing left and right.

It can be set up for a specific memory cgroup v2. Event files on v2 are based on more standard poll or inotify APIs so they don't need such a (cgroup specific) demo. Additionally, the demo program lists individual events, so it'd be a maintenance burden to keep them in sync with the kernel implementation. My .02€, Michal
