Dedicated work queue

Here, the work queue is represented as an instance of struct workqueue_struct. The work to be queued into the work queue is represented as an instance of struct work_struct. There are four steps involved prior to scheduling your work in your own kernel thread:

1. Declare/initialize a struct workqueue_struct
2. Create your work function
3. Create a struct work_struct so that your work function will be embedded into it
4. Embed your work function in the work_struct
