BugLink: https://launchpad.net/bugs/1855337 Enable CONFIG_DEBUG_NOTIFIERS to ensure that notifier functions are present in the core kernel text or module text sections before calling those functions. If an invalid function pointer is detected, a warning is issued and the function is not called. This helps in attack prevention and detection.
