o So far noop, deadline and AS had one common structure called *_data which contained both the queue information where requests are queued and also common data used for scheduling. This patch breaks down this common structure in two parts, *_queue and *_data. This is along the lines of cfq where all the reuquests are queued in queue and common data and tunables are part of data. o It does not change the functionality but this re-organization helps once noop, deadline and AS are changed to use hierarchical fair queuing. o looks like queue_empty function is not required and we can check for q->nr_sorted in elevator layer to see if ioscheduler queues are empty or not.
