Hi Jens,
It will be helpful to trace the iocg's whole state, including active and
idle state. And we can easily expand the original iocost_iocg_activate
trace event to support a state trace class, including active and idle
state tracing.

Accumulate unused quota from previous periods, thus accumulated
bandwidth runtime can be used in the following periods. During
accumulation, take care of runtime overflow. Previous non-burstable

In this patch, we introduce the notion of CFS bandwidth burst. Unused
"quota" from pervious "periods" might be accumulated and used in the
following "periods". The maximum amount of accumulated bandwidth is
bounded by "burst". And the maximun amount of CPU a group can consume in

Introduce statistics exports for the burstable cfs bandwidth
controller.
The following exports are included:
current_bw: current runtime in global pool
nr_burst: number of periods bandwidth burst occurs
burst_time: cumulative wall-time that any cpus has
used above quota in
The CFS bandwidth controller limits CPU requests of a task group to
quota during each period. However, parallel workloads might be bursty
so that they get throttled. And they are latency sensitive at the same
time so that throttling them is undesired.
Scaling up period and quota allows greater
