From 28298fd3d9df6685c069fa0d03398c8c585a83ea Mon Sep 17 00:00:00 2001 From: =?utf8?q?Beno=C3=AEt=20Canet?= Date: Fri, 5 Sep 2014 15:46:17 +0200 Subject: [PATCH] block: rename BlockAcctType members to start with BLOCK_ instead of BDRV_ MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The middle term goal is to move the BlockAcctStats structure in the device models. (Capturing I/O accounting statistics in the device models is good for billing) This patch make a small step in this direction by removing a reference to BDRV.
