sk_diag_dump_icons() acquires embryo's lock by unix_state_lock_nested() to fetch its peer. The embryo's ->peer is set to NULL only when its parent listener is close()d. Then, unix_release_sock() is called for each embryo after unlinking skb by skb_dequeue(). In sk_diag_dump_icons(), we hold the parent's recvq lock, so we need not acquire unix_state_lock_nested(), and peer is always non-NULL. Let's remove unnecessary unix_state_lock_nested() and non-NULL test for peer. Signed-off-by: Kuniyuki Iwashima <kuniyu@amazon.com> Signed-off-by: Paolo Abeni <pabeni@redhat.com>
