cgroupv2: Linux's new unified control group hierarchy

FOSDEM 2017

cgroupv1 (or just "cgroups") has helped revolutionise the way that we manage and use containers over the past 8 years. A complete overhaul is coming -- cgroupv2. This talk will go into why a new control group system was needed, the changes from cgroupv1, and practical uses that you can apply to improve the level of control you have over the processes on your servers.

We will go over:

Design decisions and deviations for cgroupv2 compared to v1
Pitfalls and caveats you may encounter when migrating to cgroupv2
Discussion of the internals of cgroupv2
Practical information about how we are using cgroupv2 inside Facebook
