From 2a30307f709e6a395d23cf94837e9aae15f8e8fa Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Tue, 7 Oct 2014 13:59:17 +0200 Subject: virtio-blk: Rename VirtIOBlkConf variables to conf This is consistent with how VirtIOFOOConf variables are named elsewhere, and makes blk available for BlockBackend variables.
