Peter Rosin b09757104e lib/string.c: allow searching for NUL with strnchr
Patch series "lib/string: search for NUL with strchr/strnchr".

I noticed an inconsistency where strchr and strnchr do not behave the
same with respect to the trailing NUL.  strchr is standardised and the
kernel function conforms, and the kernel relies on the behavior.  So,
naturally strchr stays as-is and strnchr is what I change.

While writing a few tests to verify that my new strnchr loop was sane, I
noticed that the tests for memset16/32/64 had a problem.  Since it's all
about the lib/string.c file I made a short series of it all...

This patch (of 3):

strchr considers the terminating NUL to be part of the string, and NUL
can thus be searched for with that function.  For consistency, do the
same with strnchr.

README

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.
