Hi Peter,
> Subject: [PATCH] selftests/resctrl: Use correct exit code when tests fail
>
> Use ksft_finished() after running tests so that resctrl_tests doesn't return exit
> code 0 when tests fail.
>
> Consequently, report the MBA and MBM tests as skipped when running on
> non-Intel hardware, otherwise resctrl_tests will exit with a failure code.
