Workqueue is designed to supply sufficient concurrency for such use cases and it has been doing so for all other in-kernel users for quite some time now. If you're not getting concurrency in the above scenario, either you've found a bug in workqueue or you did something wrong. If you have a scenario not working for you, please post the code.
