Message-Id: <1391156646-11981-2-git-send-email-nicolas.dichtel@6wind.com> Date: Fri, 31 Jan 2014 09:24:05 +0100 From: Nicolas Dichtel <nicolas.dichtel@...nd.com> To: rostedt@...dmis.org Cc: linux-kernel@...r.kernel.org, netdev@...r.kernel.org, stable@...r.kernel.org, williams@...hat.com, lclaudio@...g.org, jkacur@...hat.com, willemb@...gle.com, Nicolas Dichtel <nicolas.dichtel@...nd.com> Subject: [PATCH linux-3.10.y v2 2/3] Revert "ip6tnl: fix use after free of fb_tnl_dev" This reverts commit 22c3ec552c29cf4bd4a75566088950fe57d860c4. This patch is not the right fix, it introduces a memory leak when a netns is destroyed (the FB device is never deleted).
