From mboxrd@z Thu Jan 1 00:00:00 1970 From: Pierre Morel Subject: [PATCH] 9p/trans_virtio: reset virtio device on remove Date: Thu, 9 Jul 2015 14:58:26 +0200 Message-ID: <1436446706-44314-1-git-send-email-pmorel@linux.vnet.ibm.com> Cc: v9fs-developer@lists.sourceforge.net, netdev@vger.kernel.org, linux-kernel@vger.kernel.org, mst@redhat.com, virtualization@lists.linux-foundation.org To: ericvh@gmail.com Return-path: Sender: linux-kernel-owner@vger.kernel.org List-Id: netdev.vger.kernel.org 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.
