From 3df011625135fa1c670cb8e24618fc7ca38e00b0 Mon Sep 17 00:00:00 2001 From: Nikolay Aleksandrov Date: Wed, 22 Jan 2014 14:53:37 +0100 Subject: bonding: convert all_slaves_active to use the new option API This patch adds the necessary changes so all_slaves_active would use the new bonding option API.
