This patch adds support for the io_uring command pass through, aka IORING_OP_URING_CMD, to the /dev/null driver. As with all of the /dev/null functionality, the implementation is just a simple sink where commands go to die, but it should be useful for developers who need a simple IORING_OP_URING_CMD test device that doesn't require any special hardware.

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.
