[PATCH vhost v6 0/6] refactor the params of find_vqs()

[Xuan Zhuo]

This pathset is splited from the

     http://lore.kernel.org/all/20240229072044.77388-1-xuanzhuo@linux.alibaba.com

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 patch set,
let us review these first.

The patch set try to  refactor the params of find_vqs().
Then we can just change the structure, when introducing new
features.

Thanks.
