However, this function is intrinsically tied to the lifetime rules and allocation scheme of i915_request and having it in intel_engine_cs.c leaks details of i915_request. We have an abstraction leak either way. Since i915_request's allocation scheme is far more subtle than the simple pointer that is intel_engine_cs.request_pool, it's probably better to keep i915_request's details to itself.
