That may needs some cycles to discuss. But that notifies too many people.
But just the four commits need to notify so many people.
And four commits are independent. So I split that
Now, we pass multi parameters to find_vqs. These parameters
may work for transport or work for vring.
And find_vqs has multi implements in many places:
arch/um/drivers/virtio_uml.c
drivers/platform/mellanox/mlxbf-tmfifo.c
drivers/remoteproc/remoteproc_virtio.c
drivers/s390/virtio/virtio_ccw.c
Now, we pass multi parameters to vring_create_virtqueue. These parameters
may from transport or from driver.
vring_create_virtqueue is called by many places.
Every time, we try to add a new parameter, that is difficult.
If parameters from the driver, that should directly be passed to vring.
Then
As the refactor of find_vqs()/vring_new_virtqueue()/vring_create_virtqueue
the struct cfg/tp_cfg are passed to vring.
This patch refactors the vring by these structures. This can simplify
the code.

Just like find_vqs(), it is time to refactor the
vring_new_virtqueue(). We pass the similar struct to
vring_new_virtqueue.
