dependent KUnit test.

+KUnit debugfs representation
+============================
+When kunit test suites are initialized, they create an associated directory
+in /sys/kernel/debug/kunit/<test-suite>. The directory contains one file
+
+- results: "cat results" displays results of last test run
+
+The debugfs representation is primarily of use when kunit test suites are
+run in a native environment, either as modules or builtin. Having a way
+to display results like this is valuable as otherwise results can be
+intermixed with other events in dmesg output.
