Jan Kara 7684fbde45 bfq: Use only idle IO periods for think time calculations ... Currently whenever bfq queue has a request queued we add now - last_completion_time to the think time statistics. This is however misleading in case the process is able to submit several requests in parallel because e.g. if the queue has request completed at time T0 and then queues new requests at times T1, T2, then we will add T1-T0 and T2-T0 to think time statistics which just doesn't make any sence (the queue's think time is penalized by the queue being able to submit more IO). So add to think time statistics only time intervals when the queue had no IO pending.
