From 8ee79e707a005c9274df7ce34265bb7d008b8cef Mon Sep 17 00:00:00 2001 From: Kevin Wolf Date: Wed, 4 Jun 2014 15:09:35 +0200 Subject: block: Catch backing files assigned to non-COW drivers Since we parse backing.* options to add a backing file from the command line when the driver didn't assign one, it has been possible to have a backing file for e.g. raw images (it just was never accessed). This is obvious nonsense and should be rejected.
