      "message": "cpu: rewrite cpu-notifier-error-inject module\n\nRewrite existing cpu-notifier-error-inject module to use debugfs based new\nframework.\n\nThis change removes cpu_up_prepare_error and cpu_down_prepare_error module\nparameters which were used to specify error code to be injected.  We could\nkeep these module parameters for backward compatibility by module_param_cb\nbut it seems overkill for this module.\n\nThis provides the ability to inject artifical errors to CPU notifier chain\ncallbacks.  It is controlled through debugfs interface under\n/sys/kernel/debug/notifier-error-inject/cpu\n\nIf the notifier call chain should be failed with some events notified,\nwrite the error code to \"actions/\u003cnotifier event\u003e/error\".\n\nExample1: inject CPU offline error (-1 \u003d\u003d -EPERM)\n\n\t# cd /sys/kernel/debug/notifier-error-inject/cpu\n\t# echo -1 \u003e actions/CPU_DOWN_PREPARE/error\n\t# echo 0 \u003e /sys/devices/system/cpu/cpu1/online\n\tbash: echo: write error: Operation not permitted\n\nExample2: inject CPU online error (-2 \u003d\u003d -ENOENT)\n\n\t# cd /sys/kernel/debug/notifier-error-inject/cpu\n\t# echo -2 \u003e actions/CPU_UP_PREPARE/error\n\t# echo 1 \u003e /sys/devices/system/cpu/cpu1/online\n\tbash: echo: write error: No such file or directory\n\nSigned-off-by: Akinobu Mita \u003cakinobu.mita@gmail.com\u003e\nCc: Pavel Machek \u003cpavel@ucw.cz\u003e\nCc: \"Rafael J.
