Subject: [PATCH] kunit: Kconfig: enable a KUNIT_RUN_ALL fragment
Date:   Fri,  1 May 2020 10:35:10 +0200
Message-Id: <20200501083510.1413-1-anders.roxell@linaro.org>

Precedence: bulk

Make it easier to enable all KUnit fragments.  This is needed for kernel
test-systems, so its easy to get all KUnit tests enabled and if new gets
added they will be enabled as well.  Fragments that has to be builtin
will be missed if CONFIG_KUNIT_RUN_ALL is set as a module.

Adding 'if !KUNIT_RUN_ALL' so individual test can be turned of if
someone wants that even though KUNIT_RUN_ALL is enabled.
