Even though gup_benchmark.c has code to handle the -w command-line option, the "w" is not part of the getopt string. It looks as if it has been missing the whole time. On my machine, this leads naturally to the following predictable result: $ sudo ./gup_benchmark -w ./gup_benchmark: invalid option -- 'w' ...which is fixed with this commit.

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.
