Since this is only called when ref_trace_final_put tracepoint is enabled,
you can use the direct call that doesn't use the static_branch(). The above
should be:
//Wrapper function for functions defined entirely in header files
void do_ref_trace_final_put(unsigned long caller, const char *fn, const void *obj)
{
trace_call__ref_trace_final_put(caller, fn, obj);
}
