From 02727b3014f58b63b589176a191a0ced5def4a65 Mon Sep 17 00:00:00 2001 From: Kevin Wolf Date: Tue, 26 Jun 2018 09:48:19 +0200 Subject: [PATCH 111/268] job: Move .complete callback to Job RH-Author: Kevin Wolf Message-id: <20180626094856.6924-37-kwolf@redhat.com> Patchwork-id: 81084 O-Subject: [RHV-7.6 qemu-kvm-rhev PATCH v2 36/73] job: Move .complete callback to Job Bugzilla: 1513543 RH-Acked-by: Jeffrey Cody RH-Acked-by: Max Reitz RH-Acked-by: Fam Zheng This moves the .complete callback that tells a READY job to complete from BlockJobDriver to JobDriver. The wrapper function job_complete() doesn't require anything block job specific any more and can be moved to Job.
