Message-Id: <1436446706-44314-1-git-send-email-pmorel@linux.vnet.ibm.com> Date: Thu, 9 Jul 2015 14:58:26 +0200 From: Pierre Morel <pmorel@...ux.vnet.ibm.com> To: ericvh@...il.com Cc: v9fs-developer@...ts.sourceforge.net, netdev@...r.kernel.org, linux-kernel@...r.kernel.org, mst@...hat.com, virtualization@...ts.linux-foundation.org Subject: [PATCH] 9p/trans_virtio: reset virtio device on remove On device shutdown/removal, virtio drivers need to trigger a reset on the device; if this is neglected, the virtio core will complain about non-zero device status. This patch resets the status when the 9p virtio driver is removed from the system by calling vdev->config->reset on the virtio_device to send a reset to the host virtio device.
