Multiple line macro definitions where the arguments are separated by line continuations can cause checkpatch to emit invalid syntax regex tests. This can occur when a single argument is modified in a part of a patch. For example: (to not add a diff in the commit message) $ ./scripts/checkpatch.pl --git db023296f0115d2fe01fdabad54678f2b806da23 Unterminated \g... pattern in regex; <very long regex omitted> And, the test does not work correctly when these arguments are all new as the initial patch line addition "+" is used in the argument name. Fix this by stripping the line continuations and any "+" from the list of arguments.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
