[libvirt] [PATCH 11/25] qemu: blockjob: Save status XML when modifying job state
Peter Krempa

Fri Jul 12 16:05:52 UTC 2019
Now that block job data is stored in the status XML portion we need to
make sure that everything which changes the state also saves the status
XML. The job registering function is used while parsing the status XML
so in that case we need to skip the XML saving.
