Yep it certainly solves the race condition.

 		rtl8139_thread_iter (dev, tp, tp->mmio_addr);
 		rtnl_unlock ();
 	}
 
-	complete_and_exit (&tp->thr_exited, 0);

My only concern is the potential for starvation here should we fail
to obtain the RTNL.  Since any local user can hold the RTNL by issuing
rtnetlink requests, it is theoretically possible for the rtl8139 work
to be delayed indefinitely.

Cheers,
