[$] The burstable CFS bandwidth controller

The kernel's CFS bandwidth controller is an effective way of controllingjust how much CPU time is available to each control group. It can keepprocesses from consuming too much CPU time and ensure that adequate time isavailable for all processes that need it. That said, it's not entirelysurprising that the bandwidth controller is not perfect for every workload out there. Thispatch set from Huaixin Chang aims to make it work better for bursty,latency-sensitive workloads.
