[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 the max supportable by the hypervisor
...Vekatash's patch. I agree that
setting the default automatically is better than requiring the user to
set the value by hand.
