Subject: [PATCH 2/8] Move the get_net() from sock_copy()
Date: Wed, 31 Oct 2007 16:44:40 +0300	[thread overview]
Message-ID: <472886C8.5010601@openvz.org> (raw)
In-Reply-To: <472885B1.7090103@openvz.org>

The sock_copy() is supposed to just clone the socket. In a perfect
world it has to be just memcpy, but we have to handle the security
mark correctly. All the extra setup must be performed in sk_clone() 
call, so move the get_net() into more proper place.
