To begin with, this patch series relocates the cgroup example code to
the samples/cgroup directory, which is the appropriate location for such
code snippets.
Furthermore, a new memcg events listener is introduced. This
listener is a simple yet effective tool for monitoring memory events and
managing counter changes during runtime.
Additionally, as per Andrew Morton's suggestion, a helpful reminder
comment is included in the memcontrol implementation. This comment
serves to ensure that the samples code is updated whenever new events
are added.
Changes v3 since v2 at [2]:
- rename cgroup_v2_event_listener to memcg_event_listener per
Andrew's suggestion
Changes v2 since v1 at [1]:
- create new samples subdir - cgroup
- move cgroup_event_listener for cgroup v1 to samples/cgroup
- add a reminder comment to memcontrol implementation
