[Intel-gfx] [PATCH] drm/i915/gt: Close race between cacheline_retire and free

[Intel-gfx] [PATCH] drm/i915/gt: Close race between cacheline_retire and free

[Chris Wilson]

If the cacheline may still be busy, atomically mark it for future
release, and only if we can determine that it will never be used again,
immediately free it.
