From de3cb747ffac5f2a4a6bb156e7e2fd5229e688e5 Mon Sep 17 00:00:00 2001 From: Daniel Lezcano Date: Tue, 25 Sep 2007 19:16:28 -0700 Subject: [NET]: Dynamically allocate the loopback device, part 1. This patch replaces all occurences to the static variable loopback_dev to a pointer loopback_dev. That provides the mindless, trivial, uninteressting change part for the dynamic allocation for the loopback. Signed-off-by: Eric W.
