Subject: [PATCH v1 net-next 0/2] af_unix: Clean up unnecessary spin_lock(&sk->sk_peer_lock).

Except for updating sk_peer_pid/sk_peer_cred, we do not need to hold
sk_peer_lock during initialisation.

This series removes unnecessary spin_lock() and spin_unlock() in such
places.

Kuniyuki Iwashima (2):
  af_unix: Set sk_peer_pid/sk_peer_cred locklessly for new socket.
  af_unix: Don't hold client's sk_peer_lock in copy_peercred().
