From cf7732e4cc14b56d593ff53352673e1fd5e3ba52 Mon Sep 17 00:00:00 2001 From: Pavel Emelyanov Date: Wed, 10 Oct 2007 02:29:29 -0700 Subject: [NET]: Make core networking code use seq_open_private This concerns the ipv4 and ipv6 code mostly, but also the netlink and unix sockets. The netlink code is an example of how to use the __seq_open_private() call - it saves the net namespace on this private. Signed-off-by: Pavel Emelyanov Signed-off-by: David S.
