I would suggest to rephrase this to smth like "...in > case a parent cgroup requires lower cpu.util.min clamping." Right, it's slightly confusing... still I would like to call out that a parent group can enforce something on its children. What about: "... a parent cgroup allows only smaller minimum utilization values." Is that less confusing ? Otherwise I think your proposal could work too.
