From 25e40305d4f4399bc8ecf9c9b7cf43493bb40bbd Mon Sep 17 00:00:00 2001 From: "nikolay@redhat.com" Date: Thu, 18 Apr 2013 07:33:34 +0000 Subject: [PATCH] bonding: mc addresses don't get deleted on enslave failure Add bond_mc_list_flush() after err_detach as that's the first error path after the addresses are added. The main issue is the mc addresses' refcount which only gets bumped up. v2: update log message and don't move code unnecessarily Signed-off-by: Nikolay Aleksandrov Signed-off-by: David S.
