7 CFS bandwidth control is a CONFIG_FAIR_GROUP_SCHED extension which allows the
8 specification of the maximum CPU bandwidth available to a group or hierarchy.
10 The bandwidth allowed for a group is specified using a quota and period. Within
12 "quota" microseconds of CPU time. When the CPU bandwidth consumption of a

35 bandwidth restriction in place, such a group is described as an unconstrained
36 bandwidth group. This represents the traditional work-conserving behavior for
