Mostly, except that I kept it 4-argument (and used skb_copy_datagram_msg()
for name).  Matter of taste - the ones you've missed because of that are

net/appletalk/ddp.c:1761:	err = skb_copy_datagram_iovec(skb, offset, msg->msg_iov, copied);
net/ipv4/tcp.c:1836:			err = skb_copy_datagram_iovec(skb, offset,
net/ipv4/udp.c:1284:		err = skb_copy_datagram_iovec(skb, sizeof(struct udphdr),
net/ipv6/udp.c:427:			err = skb_copy_datagram_iovec(skb, sizeof(struct udphdr),
net/ipx/af_ipx.c:1808:	rc = skb_copy_datagram_iovec(skb, sizeof(struct ipxhdr), msg->msg_iov,
net/iucv/af_iucv.c:1358:	if (skb_copy_datagram_iovec(cskb, offset, msg->msg_iov, copied)) {
net/llc/af_llc.c:822:			int rc = skb_copy_datagram_iovec(skb, offset,
net/rxrpc/ar-recvmsg.c:183:		ret = skb_copy_datagram_iovec(skb, offset, msg->msg_iov, copy);
net/tipc/socket.c:1375:		res = skb_copy_datagram_iovec(buf, msg_hdr_sz(msg),
net/tipc/socket.c:1476:		res = skb_copy_datagram_iovec(buf, msg_hdr_sz(msg) + offset,
net/unix/af_unix.c:1828:	err = skb_copy_datagram_iovec(skb, skip, msg->msg_iov, size);
net/unix/af_unix.c:2033:		if (skb_copy_datagram_iovec(skb, UNIXCB(skb).consumed + skip,
net/vmw_vsock/vmci_transport.c:1776:	err = skb_copy_datagram_iovec(skb, sizeof(*dg), msg->msg_iov,

and back then I decided that 13 more converted instances might be worth keeping
it in 4-argument form...

What do you think of the trick with user_msghdr, BTW?
