Commitc1eef220c1("vsock: always call vsock_init_tables()") introduced a module_init() function without a corresponding module_exit() function. Modules with an init function can only be removed if they also have an exit function. Therefore the vsock module was considered "permanent" and could not be removed. This patch adds an empty module_exit() function so that "rmmod vsock" works. No explicit cleanup is required because: 1. Transports call vsock_core_exit() upon exit and cannot be removed while sockets are still alive. 2. vsock_diag.ko does not perform any action that requires cleanup by vsock.ko.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
