[Intel-gfx] [PATCH 18/18] drm/i915: Drop struct_mutex from around i915_retire_requests()
Chris Wilson
chris at chris-wilson.co.uk
Mon Aug 19 07:58:35 UTC 2019
We don't need to hold struct_mutex now for retiring requests, so drop it
from i915_retire_requests() and i915_gem_wait_for_idle(), finally
removing I915_WAIT_LOCKED for good.
