Lei Chen e8be225280 cgroup: blkio: adjust block io bps limit by weight ... Kernel now supports cgroup bps and iops hard limit by io-throttling. But that's not a scalable way, because block devices' bandwith is always changing over time. This patch dynamically adjusts bps limit of each blkio cgroup according to its pre-set weight. Additionally, if a process has not issued any io request during a time window, its weight will be shared by other processes until its next io request.
