From a17c17a274f24f0c0259f89d288f29b8ce0511aa Mon Sep 17 00:00:00 2001 From: Kevin Wolf Date: Tue, 24 Jan 2017 13:43:31 +0100 Subject: hw/block: Request permissions This makes all device emulations with a qdev drive property request permissions on their BlockBackend. The only thing we block at this point is resizing images for some devices that can't support it.
