From: Christoph Hellwig Date: Tue, 1 Feb 2011 20:43:48 +0000 (+0100) Subject: virtio_blk: allow re-reading config space at runtime X-Git-Url: https://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1737532fccb5bce3490f99993df31394c45da695;p=pandora-kernel.git virtio_blk: allow re-reading config space at runtime Wire up the virtio_driver config_changed method to get notified about config changes raised by the host. For now we just re-read the device size to support online resizing of devices, but once we add more attributes that might be changeable they could be added as well. Note that the config_changed method is called from irq context, so we'll have to use the workqueue infrastructure to provide us a proper user context for our changes.
