When request_queue is freezed, processes which start issuing io will be blocked, add two new field to blockinfo dump, "Freeze Depth" will tell how many queue freezing operations is going on and "Usage Counter" represents those operations who own one ref count of the queue, queue freezed succeed only when this counter drops to 0, so none zero "Freeze Depth" with none zero "Usage Counter" means queue freezeing operation is blocked by the "Usage Counter", the most common reason for this is that there is in flight ios, check "Inflight I/Os" field.
