[PATCH v2 linux-kselftest-test 0/3] kunit: support building core/tests as modules

[Alan Maguire]

The current kunit execution model is to provide base kunit functionality
and tests built-in to the kernel.  The aim of this series is to allow
building kunit itself and tests as modules.  This in turn allows a
simple form of selective execution; load the module you wish to test.
In doing so, kunit itself (if also built as a module) will be loaded as
an implicit dependency.

Because this requires a core API modification - if a module delivers
multiple suites, they must be declared with the kunit_test_suites()
macro - we're proposing this patch as a candidate to be applied to the
test tree before too many kunit consumers appear.  We attempt to deal
with existing consumers in patch 1.

Changes since v1:

- sent correct patch set; apologies, previous patch set was built
  prior to kunit move to lib/ and should be ignored.

Patch 1 consists changes needed to support loading tests as modules.
Patch 2 allows kunit itself to be loaded as a module.
Patch 3 documents module support.
