Previously, 'make run_tests -C cpu-hotplug' always PASS since cpu-on-off-test.sh
always exits 0 even though the test got some unexpected errors like below:
root@debian9:/home/lizhijian/chroot/linux/tools/testing/selftests/cpu-hotplug# make run_tests
pid 878's current affinity mask: 1
pid 878's new affinity mask: 1
CPU online/offline summary:
Cpus in online state: 0
Cpus in offline state: 0
Limited scope test: one hotplug cpu
(leaves cpu in the original state):
online to offline to online: cpu 0
./cpu-on-off-test.sh: line 83: /sys/devices/system/cpu/cpu0/online: Permission denied
offline_cpu_expect_success 0: unexpected fail
./cpu-on-off-test.sh: line 78: /sys/devices/system/cpu/cpu0/online: Permission denied
online_cpu_expect_success 0: unexpected fail
selftests: cpu-on-off-test.sh [PASS]
after this patch, the test will exit with failure once it occurs some unexpected behaviors
