From 7170be5f586b59bdcdab082778a5d9203ba7b667 Mon Sep 17 00:00:00 2001 From: Neil Horman Date: Sat, 14 Jan 2006 13:20:38 -0800 Subject: [PATCH] convert /proc/devices to use seq_file interface A Christoph suggested that the /proc/devices file be converted to use the seq_file interface. This patch does that. I've obxerved one or two installation that had sufficiently large sans that they overran the 4k limit on /proc/devices.
