From e854b61acf775a082d01d828fe3430bab0c4769f Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Christian=20K=C3=B6nig?= Date: Mon, 6 Aug 2018 12:46:41 +0200 Subject: [PATCH] drm/scheduler: bind job earlier to scheduler MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Update job earlier with the scheduler it is supposed to be scheduled on. Otherwise we could incorrectly optimize dependencies when moving an entity from one scheduler to another.
