The pkey tests define a whole lot of functions and some global variables.
A few are truly global (declared in pkey-helpers.h), but the majority are
file-scoped. Make sure those are labelled static.
Some of the pkey_{access,write}_{allow,deny} helpers are not called, or
only called when building for some architectures. Mark them
__maybe_unused to suppress compiler warnings.

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.
