The problem with notifiers is that you don't know what is being called. A function call directly in the code, where it will always be needed if configured in, is a reasonable need to not use a notifier. Although, I have to admit, if live kernel patching is configured in, it's not always needed to be called here, does it? With ftrace, the call has to be done when ftrace is configured in regardless if tracing is used or not. > > But Steven's reasoning is convincing, so I'm all up for it.
