The --defconfig option in kunit_tool was removed in [1], but the getting started and kunit_tool documentation still encouraged its use. Update those documents to reflect that it's no-longer required, and is the default behaviour if no .kunitconfig is found.

Also update a couple of places where .kunitconfig is still referred to as kunitconfig (this was changed in [2]).

-What is a kunitconfig? -====================== +What is a .kunitconfig? +=======================

It's just a defconfig that kunit_tool looks for in the base directory. kunit_tool uses it to generate a .config as you might expect. In addition, it verifies that the generated .config contains the CONFIG options in the -kunitconfig; the reason it does this is so that it is easy to be sure that a +.kunitconfig; the reason it does this is so that it is easy to be sure that a CONFIG that enables a test actually ends up in the .config.

How do I use kunit_tool? @@ -46,16 +46,9 @@ However, you most likely want to use it with the following options: - ``--timeout`` sets a maximum amount of time to allow tests to run. - ``--jobs`` sets the number of threads to use to build the kernel.
