From 7a4ddcd92ea72fdc54ebf671f3d3fcc8ba3a1ea8 Mon Sep 17 00:00:00 2001 From: dingtianhong Date: Fri, 21 Feb 2014 16:08:54 +0800 Subject: bonding: remove no longer needed lock for bond_xxx_info_query() The bond_xxx_info_query() was already in RTNL, so no need to use bond lock to protect the bond slave list, so remove it.
