Subject: [PATCH 0/5] selftests: harness: Detect illegal mixing of kselftest
 and harness functionality

Users may accidentally use the kselftest_test_result_*() functions in
their harness tests. If ksft_finished() is not used, the results
reported in this way are silently ignored.

Detect such cases and fail the test.

This should probably only go in during the next cycle.
