Per Nathan, clang catches unused "static inline" functions in C files since commit6863f5643d("kbuild: allow Clang to find unused static inline functions for W=1 build"). Linus said: > So I entirely ignore W=1 issues, because I think so many of the extra > warnings are bogus. > > But if this one in particular is causing more problems than most - > some teams do seem to use W=1 as part of their test builds - it's fine > to send me a patch that just moves bad warnings to W=2. > > And if anybody uses W=2 for their test builds, that's THEIR problem.. Here is the change to bump the warning from W=1 to W=2.

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.
