Currently running tests via KUnit tool means tweaking a .kunitconfig file, which you'd keep around locally and never commit. This changes makes it so users can pass in a path to a kunitconfig. One of the imagined use cases is having kunitconfig fragments in-tree to formalize interesting sets of tests for features/subsystems, e.g. $ ./tools/testing/kunit/kunit.py run --kunticonfig=fs/ext4/kunitconfig For now, this hypothetical fs/ext4/kunitconfig would contain CONFIG_KUNIT=y CONFIG_EXT4_FS=y CONFIG_EXT4_KUNIT_TESTS=y At the moment, it's not hard to manually whip up this file, but as more and more tests get added, this will get tedious. It also opens the door to documenting how to run all the tests relevant to a specific subsystem or feature as a simple one-liner. This can be seen as an analogue to tools/testing/selftests/*/config But in the case of KUnit, the tests live in the same directory as the code-under-test, so it feels more natural to allow the kunitconfig fragments to live anywhere. (Though, people could create a separate directory if wanted; this patch imposes no restrictions on the path).

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.
