While the new API is very simple, it is still extensible (i.e. versioned).

Sorry, I didn't follow previous discussion on this, but could you
explain what's wrong with memory notifications from memcg?
As I can see you can get pretty similar functionality using memory
thresholds on the root cgroup. What's the point?

Why should you be required to use cgroups to get VM pressure events to
userspace?

Valid point. But in fact you have it on most systems anyway.

I personally don't like to have a syscall per small feature.
Isn't it better to have a file-based interface which can be used with
normal file syscalls: open()/read()/poll()?
