12 The bandwidth allowed for a group is specified using a quota and period. Within
14 microseconds of CPU time. That quota is assigned to per-cpu run queues in
21 cfs_quota units at each period boundary. As threads consume this bandwidth it
22 is transferred to cpu-local "silos" on a demand basis. The amount transferred
