From bc444666f7e74bf1803017dc5c6fa342594c911d Mon Sep 17 00:00:00 2001 From: Nikolay Shirokovskiy Date: Fri, 27 Oct 2017 15:37:22 +0300 Subject: [PATCH] qemu: prepare blockjob complete event error usage This patch pass event error up to the place where we can use it. Error is passed only for sync blockjob event mode as we can't use the error in async mode. In async mode we just pass the event details to the client thru event API but current blockjob event API can not carry extra parameter.
