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.
Thanks.
