Add an option to wrap a zcrx instance into a file and expose it to the user space. Currently, users can't do anything meaningful with the file, but it'll be used in a next patch to import it into another io_uring instance. It's implemented as a new op called ZCRX_CTRL_EXPORT for the IORING_REGISTER_ZCRX_CTRL registration opcode.

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 reStructuredText 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.
