Merge tag 'linux-kselftest-kunit-5.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest

Pull kunit updates from Shuah Khan:

 - Add a generic kunit_resource API extending it to support resources
   that are passed in to kunit in addition kunit allocated resources. In
   addition, KUnit resources are now refcounted to avoid passed in
   resources being released while in use by kunit.

 - Add support for named resources.

 - Important bug fixes from Brendan Higgins and Will Chen
