Traditionally, each cgroup controller implemented whatever interface it wanted leading to interfaces which are widely inconsistent. Examining the requirements of the controllers readily yield that there are only a few control schemes shared among all. Two major controllers already had to implement new interface for the unified hierarchy due to significant structural changes. Let's take the chance to establish common conventions throughout all controllers. This patch defines CGROUP_WEIGHT_MIN/DFL/MAX to be used on all weight based control knobs and documents the conventions that controllers should follow on the unified hierarchy. Except for io.weight knob, all existing unified hierarchy knobs are already compliant. A follow-up patch will update io.weight. v2: Added descriptions of min, low and high knobs.
