I consider the max vs fail orthogonal to local vs hierarchical. I.e.
both entries can be in both files:

(1) misc.events.local:max number of times the cgroup's misc.max was hit
(2) misc.events.local:fail number of times operation failed in the cgroup
(3) misc.events:max number of times the cgroup's misc.max was hit in the subtree
(4) misc.events:fail number of times operation failed in the subtree

Is that too many? Admittedly, I assume (1) and (4) will be the more useful ones.
However, I'm afraid overloading "max" as suggested might be (more)
confusing. ('subtree' above := self or descendant)
