From 31dce3ccca98bc9f9eb57f8b08b008edd07661ba Mon Sep 17 00:00:00 2001 From: Kevin Wolf Date: Mon, 21 Mar 2016 11:30:57 +0100 Subject: block: throttle-groups: Use BlockBackend pointers internally As a first step towards moving I/O throttling to the BlockBackend level, this patch changes all pointers in struct ThrottleGroup from referencing a BlockDriverState to referencing a BlockBackend. This change is valid because we made sure that throttling can only be enabled on BDSes which have a BB attached.
