From dcbccbd4f1f6ad0f0e169d4b2e816e42bde06f82 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Sun, 29 Nov 2009 22:25:26 +0000 Subject: [PATCH] net: Implement for_each_netdev_reverse. I will need this shortly to implement network namespace shutdown batching. For sanity sake network devices should be removed in the reverse order they were created in. Signed-off-by: Eric W.
