1 Notifier error injection
4 Notifier error injection provides the ability to inject artificial errors to
5 specified notifier chain callbacks. It is useful to test the error handling of
14 PM notifier error injection module
18   /sys/kernel/debug/notifier-error-inject/pm/actions/<notifier event>/error
26 Example: Inject PM suspend error (-12 = -ENOMEM)::
28 	# cd /sys/kernel/debug/notifier-error-inject/pm/
29 	# echo -12 > actions/PM_SUSPEND_PREPARE/error
31 	bash: echo: write error: Cannot allocate memory
33 Memory hotplug notifier error injection module
37   /sys/kernel/debug/notifier-error-inject/memory/actions/<notifier event>/error
44 Example: Inject memory hotplug offline error (-12 == -ENOMEM)::
46 	# cd /sys/kernel/debug/notifier-error-inject/memory
47 	# echo -12 > actions/MEM_GOING_OFFLINE/error
