The patchset adds the pids of the lxc-attach process to the cgroup of the

Because this is my first patch for lxc, someone should analyze it.
If you agree with the solution then integrate it.
If there is anything i should do better in future tell me please.

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security
threats, fraudulent activity, and more. Splunk takes this data and makes
sense of it. IT sense. And common sense.
