From 8e603460fa388c89f08e359366ec9398971cf49c Mon Sep 17 00:00:00 2001 From: Veaceslav Falico Date: Tue, 18 Feb 2014 07:48:46 +0100 Subject: [PATCH] bonding: trivial: rename slave->jiffies to ->last_link_up slave->jiffies is updated every time the slave becomes active, which, for bonding, means that its link is 'up'.
