When CONFIG_MODULE_UNLOAD is disabled, the module->exit member
is not defined, causing a build failure:
kernel/module.c:4493:8: error: no member named 'exit' in 'struct module'
mod->exit = *exit;
add an #ifdef block around this.
Fixes: cf68fffb66 ("add support for Clang CFI")

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.
