From 48833071d955406ebeddc365a8df8b5cb12b035f Mon Sep 17 00:00:00 2001 From: Gonglei Date: Tue, 30 Sep 2014 14:10:36 +0800 Subject: [PATCH] virtio-9p: use aliases instead of duplicate qdev properties virtio-9p-pci all duplicate the qdev properties of their V9fsState child. This approach does not work well with string or pointer properties since we must be careful about leaking or double-freeing them. Use the QOM alias property to forward property accesses to the V9fsState child. This way no duplication is necessary.
