Vivek Goyal 58ff82f34c blkio: Implement per cfq group latency target and busy queue avg 
o So far we had 300ms soft target latency system wide. Now with the
  introduction of cfq groups, divide that latency by number of groups so
  that one can come up with group target latency which will be helpful
  in determining the workload slice with-in group and also the dynamic
  slice length of the cfq queue.
