David Gow dce19a3fed kunit: test: Make filter strings in executor_test writable
KUnit's attribute filtering feature needs the filter strings passed in
to be writable, as it modifies them in-place during parsing. This works
for the filters passed on the kernel command line, but the string
literals used in the executor tests are at least theoretically read-only
(though they work on x86_64 for some reason). s390 wasn't fooled, and
crashed when these tests were run.

Use a 'char[]' instead, (and make an explicit variable for the current
filter in parse_filter_attr_test), which will store the string in a
writable segment.

Fixes: 76066f93f1 ("kunit: add tests for filtering attributes")

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.
