Subject: [PATCH 22/34] qemu-iotests: make assert_no_active_block_jobs() common

RH-Author: Max Reitz <mreitz@redhat.com>

Patchwork-id: 56815
O-Subject: [RHEL-7.0 qemu-kvm PATCH v2 2/7] qemu-iotests: make assert_no_active_block_jobs() common
Bugzilla: 921890
RH-Acked-by: Fam Zheng <famz@redhat.com>
RH-Acked-by: Kevin Wolf <kwolf@redhat.com>
RH-Acked-by: Jeffrey Cody <jcody@redhat.com>

From: Stefan Hajnoczi <stefanha@redhat.com>

BZ: 921890

Tests 030 and 041 both use query-block-jobs to check whether any block
jobs are active.  Make this code common so that 'drive-backup' and other
new feature tests will be able to reuse it.
