From 2def16ae6b0c77571200f18ba4be049b03d75579 Mon Sep 17 00:00:00 2001 From: Eric Dumazet <eric.dumazet@gmail.com> Date: Mon, 2 Apr 2012 22:33:02 +0000 Subject: net: fix /proc/net/dev regression Commit f04565ddf52 (dev: use name hash for dev_seq_ops) added a second regression, as some devices are missing from /proc/net/dev if many devices are defined. When seq_file buffer is filled, the last ->next/show() method is canceled (pos value is reverted to value prior ->next() call) Problem is after above commit, we dont restart the lookup at right position in ->start() method. Fix this by removing the internal 'pos' pointer added in commit, since we need to use the 'loff_t *pos' provided by seq_file layer. This also reverts commit 5cac98dd0 (net: Fix corruption in /proc/*/net/dev_mcast), since its not needed anymore.
