    Subject[PATCH 0/7] notifier error injection
    Date
    This provides the ability to inject artifical errors to the following
    notifier chain callbacks. It is useful to test the error handling of
    notifier call chain failures.

    * CPU notifier
    * PM notifier
    * memory hotplug notifier
    * powerpc pSeries reconfig notifier

    We already have cpu-notifier-error-inject.ko module providing such
    functionality for the CPU notifier. However, this patch set adds
    common basic functions and consistent debugfs interface for them.

    Akinobu Mita (7):
    pm: improve error code of pm_notifier_call_chain()
    debugfs: add debugfs_create_int
    fault-injection: notifier error injection
    cpu: CPU notifier error injection
    PM: PM notifier error injection
    memory: memory notifier error injection
    powerpc: pSeries reconfig notifier error injection
