As an example for the new documentation tool, add a documentation for drm_buddy_test.

I opted to place this on a completely different directory, in order to make easier to test the feature with:

    $ make SPHINXDIRS="tests" htmldocs

I apologize that the last email included a HTML attachment of the message.

Just in case anyone was unable to receive the last email here is a copy of the message:

Hi!

This is such a cool patch series. I just have a few comments related to the output.

In the html output the tests are listed as: ktest@drm_buddy_test@...

I wonder if instead of using the file name of "drm_buddy_test" this could possibly be the suite name, "drm_buddy", as this is what users will call when using kunit.py to run the tests. Although "drm_buddy_test" is also the module name so I don't mind it too much. But in the future the file name and module name are not guaranteed to be the same for other tests.

Most preferably, there would be a reference to the kunit suite name, file name, and the module name.

This may be difficult to implement as these can all differ. I am currently working on the KUnit Attribute framework which saves the module name and I am thinking about also saving the file path as a future attribute. This could be a helpful framework for the KUnit tests specifically.

I am not sure how easy it would be to access c objects/functions using this system.

Finally, I was wondering if it is the intention to put a list of all KUnit tests that use this new feature into tests/kunit.rst or would this be broken up in some way.

Thanks! -Rae
