From dc80ca6cd6cafdee174af3c883d85e19b7fd70a5 Mon Sep 17 00:00:00 2001 From: Stefan Hajnoczi Date: Wed, 18 Jun 2014 17:58:29 +0800 Subject: virtio-blk: avoid qdev property definition duplication It becomes unwiedly to duplicate all virtio-blk qdev property definitions due to an #ifdef. The C preprocessor syntax makes it a little hard to resolve this cleanly but we can extract the #ifdef and call a macro it defines later. Avoiding duplication is important since it will only get worse when we move the x-data-plane qdev property here too. We'd have a combinatorial explosion since x-data-plane has its own #ifdef.
