From ef6dbf1e46ebd1d41ab669df5bba0bbdec6bd374 Mon Sep 17 00:00:00 2001 From: Max Reitz Date: Fri, 24 Oct 2014 15:57:34 +0200 Subject: [PATCH] blockjob: Add "ready" field When a block job signals readiness, this is currently reported only through QMP. If qemu wants to use block jobs for internal tasks, there needs to be another way to correctly detect when a block job may be completed. For this reason, introduce a bool "ready" which is set when the block job may be completed.
