Eric Dumazet b2a7309743 l2tp: prevent lockdep issue in l2tp_tunnel_register() ... [ Upstream commit b9fb10d131 ] lockdep complains with the following lock/unlock sequence: lock_sock(sk); write_lock_bh(&sk->sk_callback_lock); [1] release_sock(sk); [2] write_unlock_bh(&sk->sk_callback_lock); We need to swap [1] and [2] to fix this issue.
