+         This feature enables the scheduler to track the clamped utilization
+         of each CPU based on RUNNABLE tasks currently scheduled on that CPU.
+
+         When this option is enabled, the user can specify a min and max
+         CPU bandwidth which is allowed for each single task in a group.
+         The max bandwidth allows to clamp the maximum frequency a task
+         can use, while the min bandwidth allows to define a minimum
+         frequency a task will always use.
+
+         When task group based utilization clamping is enabled, an eventually
+         specified task-specific clamp value is constrained by the cgroup
+         specified clamp value. Both minimum and maximum task clamping cannot
+         be bigger than the corresponding clamping defined at task group level.
+
+         If in doubt, say N.
