From daa7f2f9467bc5624f04f28d4b01b88f08c6589c Mon Sep 17 00:00:00 2001 From: Kevin Wolf Date: Tue, 17 Apr 2018 12:56:07 +0200 Subject: job: Move cancelled to Job We cannot yet move the whole logic around job cancelling to Job because it depends on quite a few other things that are still only in BlockJob, but we can move the cancelled field at least.
