Subject: [PATCH v5 linux-kselftest-test 5/6] kunit: allow kunit to be loaded as a module
Date: Tue, 3 Dec 2019 12:07:47 +0000 [thread overview]
Message-ID: <1575374868-32601-6-git-send-email-alan.maguire@oracle.com> (raw)
In-Reply-To: <1575374868-32601-1-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.
