Subject: [PATCH] drm/i915: Make global seqno known in i915_gem_request_execute tracepoint
Git-commit: fa89782b4f9c40d40e3f7d9ad7ef14e0bb0c3ca0
Patch-mainline: v4.16-rc4
No-fix: 158863fb50968c0ae85e87a401221425c941b9f0
References: FATE#322643 bsc#1055900
Commit fe49789fab97 ("drm/i915: Deconstruct execute fence") re-arranged
the code and moved the i915_gem_request_execute tracepoint to before the
global seqno is assigned to the request.
We need to move the tracepoint a bit later so this information is once
again available.
