I want to use a real time kernel thread So I created a workqueue (create_workqueue) and changed its pritority to SCHED_FF. This will serve the purpose of http://www.falsig.org/simon/blog/2013/07/10/real-time-linux-kernel-drivers-part-3-the-better-implementation/ ? if a user thread is blocked on a poll(), is there any performance degrade if i woke it from the above workqueue thread ?
