From bd33acc3cc525972ac779067e98efb26516c5b94 Mon Sep 17 00:00:00 2001 From: Amerigo Wang Date: Sun, 6 Mar 2011 21:58:46 +0000 Subject: bonding: move procfs code into bond_procfs.c V2: Move #ifdef CONFIG_PROC_FS into bonding.h, as suggested by David. bond_main.c is bloating, separate the procfs code out, move them to bond_procfs.c Signed-off-by: WANG Cong Reviewed-by: Jiri Pirko Signed-off-by: Andy Gospodarek Signed-off-by: David S.
