What you are saying is that we have inefficient notification mechanism
that hammers everyone's boot time significantly, and no current path
to resolve it. What can I do get us efficient cgroup release
notifications soon?
This patch-set is a no-op if one doesn't subscribe from the userspace
and has no other side effects that I can trivially see and is very
similar in-spirit to other notifications that proc-connector
generates. E.g. /proc/pid/comm is exposed as a file, yet there is proc
connector notification as well about comm name changes. Maybe Evgeniy
can chip in, if such a notification would be beneficial to
proc-connector.

I understand your need in a new notifications related to cgroups,
although I would rather put it into separate module than proc connector - 
I'm pretty sure there will be quite alot of extensions in this module in the future.

But if you do want to extend proc connector module, I'm ok with it, but it should
go via its maintainer.
