Subject: Why ECONNREFUSED from unix_dgram_sendmsg?

What is unix_dgram_sendmsg trying to tell me here?

        if (sock_flag(other, SOCK_DEAD)) {
                /*
                 *      Check with 1003.1g - what should
                 *      datagram error
                 */
                unix_state_unlock(other);
                sock_put(other);

                err = 0;
                unix_state_lock(sk);
                if (unix_peer(sk) == other) {
                        unix_peer(sk) = NULL;
                        unix_state_unlock(sk);

                        unix_dgram_disconnected(sk, other);
                        sock_put(other);
                        err = -ECONNREFUSED;

I'm getting this intermittently on a seqpacket socket when the other
end dies.  Shouldn't this be -ECONNRESET?

git blame doesn't tell me anything here -- this code predates git.
