Subject: [PATCH 3.13 020/212] macvlan: Fix lockdep warnings with stacked macvlan devices
Date: Tue, 17 Jun 2014 14:41:54 -0700 [thread overview]
Message-ID: <1403041506-13646-21-git-send-email-kamal@canonical.com> (raw)
In-Reply-To: <1403041506-13646-1-git-send-email-kamal@canonical.com>
3.13.11.4 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Vlad Yasevich <vyasevic@redhat.com>
[ Upstream commit c674ac30c549596295eb0a5af7f4714c0b905b6f ]
Macvlan devices try to avoid stacking, but that's not always
successfull or even desired. As an example, the following
configuration is perefectly legal and valid:
eth0 <--- macvlan0 <---- vlan0.10 <--- macvlan1
However, this configuration produces the following lockdep
trace:
