Subject: [PATCH net-next 05/26] bonding: populate neighbour's private on enslave
Date: Mon,  9 Sep 2013 22:16:23 +0200	[thread overview]
Message-ID: <1378757804-3159-6-git-send-email-vfalico@redhat.com> (raw)
In-Reply-To: <1378757804-3159-1-git-send-email-vfalico@redhat.com>

Use the new provided function when attaching the lower slave to populate
its ->private with struct slave *new_slave. Also, move it to the end to
be able to 'find' it only after it was completely initialized, and
deinitialize in the first place on release.
