There were a few attempts at changing behavior of the match_string() helpers (i.e. 'match_string()' & 'sysfs_match_string()'), to change & extend the behavior according to the doc-string. But the simplest approach is to just fix the doc-strings. The current behavior is fine as-is, and some bugs were introduced trying to fix it. As for extending the behavior, new helpers can always be introduced if needed. The match_string() helpers behave more like 'strncmp()' in the sense that they go up to n elements or until the first NULL element in the array of strings. This change updates the doc-strings with this info.

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.
