I'm looking to enable -Wmissing-variable-declarations behind W=1. 0day
bot spotted the following instance:
arch/um/drivers/port_kern.c:147:14: warning: no previous extern
declaration for non-static variable 'port_work'
[-Wmissing-variable-declarations]
DECLARE_WORK(port_work, port_work_proc);
^
arch/um/drivers/port_kern.c:147:1: note: declare 'static' if the
variable is not intended to be used outside of this translation unit
DECLARE_WORK(port_work, port_work_proc);
^
This symbol is not referenced by more than one translation unit, so give
it static storage.

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.
