This is redundant: virtio_cread_feature() checks the feature.
So, either:
if (virtio_has_feature(vdev, VIRTIO_BLK_F_MQ))
virtio_cread(vdev, struct virtio_blk_config, num_queues,
&num_vqs);
else
num_vqs = 1;
Or:
err = virtio_cread_feature(vdev, VIRTIO_BLK_F_MQ,
struct virtio_blk_config, num_queues,
&num_vqs);
if (err)
num_vqs = 1;
Otherwise, the patch looks pretty straight-forward.
Cheers,
Rusty.
