Our connection state spans sockets that can disconnect and reconnect. While sockets are connected we store the socket's remote address in the connection's peername and we clear it as sockets disconnect. Fencing wants to know the last connected address of the mount. It's a bit of metadata we know about the mount that can be used to find it and fence it. As we store the peer address we also stash it away as the last known peer address for the socket. Fencing can then use that instead of the current socket peer address which is guaranteed to be uninitialized because there's no socket connected. Signed-off-by: Zach Brown <zab@versity.com>
