[PATCH] virtio-blk: Initialize blkqueue depth from virtqueue size
virtio-blk set the default queue depth to 64 requests, which was
insufficient for high-IOPS devices. Instead set the blk-queue depth to
the device's virtqueue depth divided by two (each I/O requires at least
two VQ entries).

[PATCH] virtio-blk: make the queue depth configurable
...IOPS which can be sustained. So make the queue depth something which
