Subject: [PATCH v15 14/18] kunit: defconfig: add defconfigs for building KUnit tests
Date: Fri, 23 Aug 2019 18:34:21 -0700
Message-ID: <20190824013425.175645-15-brendanhiggins@google.com> (raw)
In-Reply-To: <20190824013425.175645-1-brendanhiggins-hpIqsD4AKlfQT0dZR+AlfA@public.gmane.org>

Add defconfig for UML and a fragment that can be used to configure other
architectures for building KUnit tests. Add option to kunit_tool to use
a defconfig to create the kunitconfig.
