Kuniyuki Iwashima 22e5751b05 af_unix: Don't use spin_lock_nested() in copy_peercred(). ... When (AF_UNIX, SOCK_STREAM) socket connect()s to a listening socket, the listener's sk_peer_pid/sk_peer_cred are copied to the client in copy_peercred(). Then, two sk_peer_locks are held there; one is client's and another is listener's. However, the latter is not needed because we hold the listner's unix_state_lock() there and unix_listen() cannot update the cred concurrently. Let's drop the unnecessary spin_lock() and use the bare spin_lock() for the client to protect concurrent read by getsockopt(SO_PEERCRED).
