if you remove the test on FF_BRIDGE_PORT, and br_port_get_rcu never returns NULL, the problem is fixed. but the codes in mainline is still bugged, am i right?? by the way, kernel-stable 3.0 and 3.4 tree also have this bug, and is very easily to reproduce.
Commit 00cfec37484761a4 has to be backported anyway, if not already backported. I would rather fix things properly, instead of adding defensive code.
