Subject: linux-next: manual merge of the security-testing tree with the net
 tree

Hi James,

Today's linux-next merge of the security-testing tree got a conflict in
security/smack/smack_lsm.c between commit
3610cda53f247e176bcbb7a7cca64bc53b12acdb ("af_unix: Avoid socket->sk NULL
OOPS in stream connect security hooks") from the net tree and commit
b4e0d5f0791bd6dd12a1c1edea0340969c7c1f90 ("Smack: UDS revision") from the
security-testing tree.

I fixed it up (I think - see below) and can carry the fix as necessary.
