I'm looking for some reference documentation to explain what each of the settings are, for each control group.

For example, there's cpuset.cpus, I think setting this to 0 means use all CPUs, setting it to 1 limits you to 1 core. And cpuset.shares, how is that configured exactly?

Surely there's a reference doc that simply explains each of the settings somewhere right? Anyone have a link?

A big thanks to Red Hat, I finally tracked down the reference documentation I was looking for in their documentation. I expect that there's no difference between Red Hat and other distros on this point.

cgroups is still quite in flux in the Linux kernel. Probably the best documentation is LWN's coverage, perhaps H-online or Kernelnewbies have something to say. Currently systemd is the most prolific user.
