From: "Steven Rostedt (Google)" <rostedt@xxxxxxxxxxx> If the vals is NULL (which is valid), the traceeval_insert() macro calls traceeval_insert_size() with sizeof(vals)/sizeof(vals[0]) to get the number of vals in the array. But this does not make sense with a NULL value. Check for NULL and if vals is NULL then pass in zero.
