Currently, when pids.max limit is breached in the hierarchy, the event is counted and reported in the cgroup where the forking task resides.

This decouples the limit and the notification caused by the limit making it hard to detect when the actual limit was effected.

Let's introduce new events: max The number of times the limit of the cgroup was hit.

 max.imposed
The number of times fork failed in the cgroup because of self
or ancestor limit.

The whole series make sense to me. I'm not sure about max.imposed field name. Maybe a name which clearly signfies rejection of forks would be clearer? Johannes, what do you think?

Thanks.
