Julian Nastasov found the bug in ip_conn_unhash, bug in ip_vs_edit_dest?

["Brett E." <brettspamacct@xxxxxxxxxxxxx>]

He emailed me a patch which fixed the problem I was having, he said he 
would include it in the next release.
Also, I have a question, ip_vs_edit_dest calls update_service without 
acquiring a lock, is this a bug, shouldn't it acquire the write lock?
