Subject: [PATCH 096/268] job: Move state transitions to Job
RH-Author: Kevin Wolf <kwolf@redhat.com>
Message-id: <20180626094856.6924-22-kwolf@redhat.com>
Patchwork-id: 81093
O-Subject: [RHV-7.6 qemu-kvm-rhev PATCH v2 21/73] job: Move state transitions to Job
Bugzilla: 1513543
RH-Acked-by: Jeffrey Cody <jcody@redhat.com>
RH-Acked-by: Max Reitz <mreitz@redhat.com>
RH-Acked-by: Fam Zheng <famz@redhat.com>
This moves BlockJob.status and the closely related functions
(block_)job_state_transition() and (block_)job_apply_verb to Job. The
two QAPI enums are renamed to JobStatus and JobVerb.
