the CPU usage(including iowait) is customer's criteria. 
and i try to change the io_schedule_timeout to schedule_timeout, the cpu iowait
value have the same high value, Any other suggestions? thanks very much in
advance.

and our customer is pending on this issue fix, Is it possible to set to the
high priority? thanks very much.
