We _never_ add any exports for APIs that don't have any in-kernel users. That's a hard rule that we've had forever. As such, there is not a path for entry for this particular patch right now. It should be submitted alongside the upstream submission request for the code using it, as a preparatory patch. -- Jens Axboe
