Great! I think we should place those blk_delay_queue() calls under the if (rq), that should workd to and be more optimal. Can I ask you to check that, too? So: if (rq) { blk_requeue_request(q, rq); blk_delay_queue(q, msecs_to_jiffies(3)); } in both locations. -- Jens Axboe -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
