[PATCH] finish fixing cgroup config option conversion

[Glauber Costa <glommer@parallels.com>]

Andrew, please fold it in your patch so we don't break the build.  Some
of them are needed not to break the build (in net and swap).  And I am
taking the change to patch the Documentation file to reflect reality.
