[PATCH 50/55] drm/i915: Rename intel_context.active to .inflight

Chris Wilson chris at chris-wilson.co.uk
Mon Apr 15 09:15:45 UTC 2019


Rename the engine this HW context is currently active upon (that we are
flying upon) to disambiguate between the mixture of different active
terms (and prevent conflict in future patches).
