And since I could still be misunderstanding your intent here, if you mean that you want to submit sqe to ring1 with ring2 being the target, then I'm not sure that would be very helpful. The submitting task is the owner of the request, and will ultimately be the one that ends up running eg task_work associated with the request. It's not really a good way to shift work from one ring to another, if the setup is such that the rings are tied to a thread and the threads are in turn mostly tied to a CPU or group of CPUs. -- Jens Axboe
