From a2f3be17c07ad9bd45ab300f79642ecb39cfb553 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ilpo=20J=C3=A4rvinen?= Date: Mon, 3 May 2010 03:22:18 +0000 Subject: [PATCH] unix/garbage: kill copy of the skb queue walker MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Worse yet, it seems that its arguments were in reverse order.
