From: Pavel Emelyanov <xemul@...nvz.org>
To: Eric Dumazet <dada1@...mosbay.com>
CC: Linux Netdev List <netdev@...r.kernel.org>
Subject: [PATCH net-2.6.26 4/5][SOCK]: Forget the proto.inuse pcounter.
Just drop it from the proto structure and remove all initializations
from protocols.
Signed-off-by: Pavel Emelyanov <xemul@...nvz.org>
