Because we override RUN_TESTS. > Hello Michael, I have done a small experiment with timeout=1 in settings and use run-parts to run the executables, it looks like this change won't affect run-parts. Not quite sure about the RUN_TESTS you mentioned here, we're testing it with command like: sudo make -C linux/tools/testing/selftests TARGETS=powerpc run_tests And the timeout setting will take effect with this.
