From 284f42a520cd9f5905abac2fa50397423890de8f Mon Sep 17 00:00:00 2001 From: Jens Freimann Date: Wed, 20 Nov 2019 16:49:48 +0100 Subject: net/virtio: fix dev_unplug_pending .dev_unplug_pending is set up by virtio-net code indepent of failover support was set for the device or not. This gives a wrong result when we check for existing primary devices in migration code. Fix this by actually calling dev_unplug_pending() instead of just checking if the function pointer was set. When the feature was not negotiated dev_unplug_pending() will always return false. This prevents us from going into the wait-unplug state when there's no primary device present.
