From cc3375607d79c368ec1dbeb4c2922371fffa19ca Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Mon, 19 Aug 2019 19:44:03 +0100 Subject: drm/i915: Use 0 for the unordered context Since commit 078dec3326e2 ("dma-buf: add dma_fence_get_stub") the 0 fence context became an impossible match as it is used for an always signaled fence. We can simplify our timeline tracking by knowing that 0 always means no match.
