find_vqs() adds a new parameter sizes to specify the size of each vq vring. NULL as sizes means that all queues in find_vqs() use the maximum size. A value in the array is 0, which means that the corresponding queue uses the maximum size. In the split scenario, the meaning of size is the largest size, because it may be limited by memory, the virtio core will try a smaller size. And the size is power of 2.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
