In the case I outlined below, for backwards compatibility. What I
actually mean is that memcg *currently* allows arbitrary notifications.
One way to merge those, while moving to a saner 3-point notification, is
to still allow the old writes and fit them in the closest bucket.

Yeah, but I'm wondering why three is the right answer.

This is unrelated to what I am talking about.
I am talking about pre-defined values with a specific event meaning (in
his patchset, 3) vs arbitrary numbers valued in bytes.

Right, and I don't see how you can map the memcg thresholds onto Anton's 
scheme

BTW, there's interface for OOM notification in memcg. See oom_control.
I guess other pressure levels can also fit to the interface.
