OK, our function declarations match up.  Good.

The error messages you sent complain about argument 3 of
marker_probe_register() and argument 2 of marker_probe_unregister().
Both of those are 'marker_probe_func *'.  So, here's my declaration of
'marker_probe_func' from linux/marker.h:

----
typedef void marker_probe_func(void *probe_private, void *call_private,

                const char *fmt, va_list *args);

----

Can you show me your declaration?
