To unify the return code of resctrl_tests with the return code of selftest set, return KSFT_SKIP (4) if resctrl filessystem is not supported or resctrl is not run as root.
Could you please elaborate how changing ksft_exit_fail_msg() to ksft_exit_skip() accomplishes the goal of unifying the return code? What is wrong with using ksft_exit_fail_msg()?
In selftest framwork, if a test need root privileges, but it is run as user privileges, the test result will counted as a SKIP item, instead of a FAIL item.
For example, (1)tools/testing/selftests/mqueue/mq_open_tests.c 267 if (getuid() != 0) 268 ksft_exit_skip("Not running as root, but almost all tests " 269 "require root in order to modify\nsystem settings. " 270 "Exiting.\n");
(2)tools/testing/selftests/bpf/test_kmod.sh 5 ksft_skip=4 6 7 msg="skip all tests:" 8 if [ "$(id -u)" != "0" ]; then 9 echo $msg please run this as root >&2 10 exit $ksft_skip 11 fi
