A large user of this library (unsurprisingly) is the containerd daemon, and specifically through the CRI entrypoint. There's quite a few stats we gather that are never bubbled up the chain when requested through that funnel. The stats never used are: MemoryEvents, Rdma, Hugetlb, and IO. We should likely do the same to cg1, but if we want to add it to the Cgroup interface it'd be a breaking change. Signed-off-by: Danny Canter <danny@dcantah.dev>

I like this idea. I was thinking adding new function to cgroupv2 object to get event information.
This solution looks good!

I actually went down this rabbit hole because I wanted a way to solely just get the memory events also.. But this seemed a little bit easier to digest than a new method that solely returned those 😄

We should likely do the same to cg1 (#370), but if we want to add it to the Cgroup interface it'd be a breaking change.
