Query: Notifier support for callback profiling

Hi ,

Can we profile driver specific notifier callback from Linux notifier.
Sometimes we need to debug which callback is taking more time or where it is stuck.
If kernel/notifier.c provide generic mechanism to profile callbacks that will
save profiling individual callbacks.
