To check that tests are passing we must parse the kselftest runner output. It is much more convenient to check the return value of the runner instead: 0 is OK, and 1 implies one or more errors. This has an impact on the kselftest's gen_tar bundle and the run_tests make target. Backporting this change would be useful to consistently test older kernels as well.
