And the functions they call?

Yes. But you only really need it for the actual callback, not the bulk
of stop_machine_run() (which calls scheduler and lots of other stuff)
The actual callback should be pretty limited already so it shouldn't
be a big limitation.


Hmm. Seems dangerous to rely on this, because functions could change from inline to out of line without people noticing that it affects this very corner case for kprobes + paravirt + stop_machine. Is there a way to cascade the __kprobes declaration to all called functions, perhaps with a static checker, like sparse?
