Defer the transfer from the client's timeline onto the execution timeline from the point of readiness to the point of actual submission. For example, in execlists, a request is finally submitted to hardware when the hardware is ready, and only put onto the hardware queue when the request is ready. By deferring the transfer, we ensure that the timeline is maintained in retirement order if we decide to queue the requests onto the hardware in a different order than fifo. v2: Rebased onto distinct global/user timeline lock classes. v3: Play with the position of the spin_lock(). v4: Nesting finally resolved with distinct sw_fence lock classes.
