There are tools/testing/selftests using the notifier error injection features
for CPU and memory notifiers.
- * tools/testing/selftests/cpu-hotplug/on-off-test.sh
- * tools/testing/selftests/memory-hotplug/on-off-test.sh
+ * tools/testing/selftests/cpu-hotplug/cpu-on-off-test.sh
+ * tools/testing/selftests/memory-hotplug/mem-on-off-test.sh
These scripts first do simple online and offline tests and then do fault
injection tests if notifier error injection module is available.
