From: Christian König Date: Mon, 6 Aug 2018 10:46:41 +0000 (+0200) Subject: drm/scheduler: bind job earlier to scheduler X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=e854b61acf775a082d01d828fe3430bab0c4769f;p=openwrt%2Fstaging%2Fblogic.git drm/scheduler: bind job earlier to scheduler 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.
