From 9caff1e7b761c28018bf1858f6661439b4055f51 Mon Sep 17 00:00:00 2001 From: Veaceslav Falico Date: Wed, 25 Sep 2013 09:20:14 +0200 Subject: [PATCH] bonding: make bond_for_each_slave() use lower neighbour's private It needs a list_head *iter, so add it wherever needed. Use both non-rcu and rcu variants. CC: Jay Vosburgh CC: Andy Gospodarek CC: Dimitris Michailidis Signed-off-by: Veaceslav Falico Signed-off-by: David S.
