From b20903f2a9ee5bd9ca80ad72867c8d137aaf4d62 Mon Sep 17 00:00:00 2001 From: "nikolay@redhat.com" Date: Tue, 6 Aug 2013 12:40:16 +0200 Subject: [PATCH] bonding: unwind on bond_add_vlan failure In case of bond_add_vlan() failure currently we'll have the vlan's refcnt bumped up in all slaves, but it will never go down because it failed to get added to the bond, so properly unwind the added vlan if bond_add_vlan fails.
