The function of this patch is to add an nr_sched_batch interface under
/sys/block/sdx/queue/, which can be used to set the number of batching
requests. Of course, the default value is nr_requests and will follow
nr_request when it has not been changed.

How can reducing the number of batched requests increase performance?

Please provide performance numbers.

Thanks,

Bart.
