From 4bff28b81a0ddb48a09d279e99ab847e8a292506 Mon Sep 17 00:00:00 2001 From: Max Reitz Date: Tue, 28 Mar 2017 22:51:28 +0200 Subject: block: Add errp to BD.bdrv_truncate() Add an Error parameter to the block drivers' bdrv_truncate() interface. If a block driver does not set this in case of an error, the generic bdrv_truncate() implementation will do so. Where it is obvious, this patch also makes some block drivers set this value.
