[Intel-gfx] [PATCH] drm/i915: Flush execution tasklets before checking request status

[Chris Wilson]

Rather than flushing the submission tasklets just before we sleep, flush
before we check the request status. Ideally this gives us a moment to
process the tasklets after sleeping just before we timeout.
