Convert test_string.c to KUnit so it can be easily run with everything else. Additional text context is retained for failure reporting. For example, when forcing a bad match, we can see the loop counters reported for the memset() tests: [09:21:52] # test_memset64: ASSERTION FAILED at lib/string_kunit.c:93 [09:21:52] Expected v == 0xa2a1a1a1a1a1a1a1ULL, but [09:21:52] v == -6799976246779207263 (0xa1a1a1a1a1a1a1a1) [09:21:52] 0xa2a1a1a1a1a1a1a1ULL == -6727918652741279327 (0xa2a1a1a1a1a1a1a1) [09:21:52] i:0 j:0 k:0 [09:21:52] [FAILED] test_memset64 Currently passes without problems: $ ./tools/testing/kunit/kunit.py run string ...

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.
