[   51.680236] ===============================
[   51.681914] [ INFO: suspicious RCU usage. ]
[   51.683610] 3.8.0-rc6-next-20130206-sasha-00028-g83214f7-dirty #276 Tainted: G        W
[   51.686703] -------------------------------
[   51.688281] net/ipv6/ip6_flowlabel.c:671 suspicious rcu_dereference_check() usage!

we should use rcu_dereference_bh() when we hold rcu_read_lock_bh().
