Subject: [PATCH v2 linux-kselftest-test 2/3] kunit: allow kunit to be loaded as a module
Date: Tue,  8 Oct 2019 15:55:45 +0100	[thread overview]
Message-ID: <1570546546-549-3-git-send-email-alan.maguire@oracle.com> (raw)
In-Reply-To: <1570546546-549-1-git-send-email-alan.maguire@oracle.com>

Making kunit itself buildable as a module allows for "always-on"
kunit configuration; specifying CONFIG_KUNIT=m means the module
is built but only used when loaded.  Kunit test modules will load
kunit.ko as an implicit dependency, so simply running
"modprobe my-kunit-tests" will load the tests along with the kunit
module and run them.
