Patches are welcome, of course.
Threaded IRQs are no magic bullet. They can only help to push a problem down the priority ladder, curing a problem symptom where possible. Nevertheless, threaded IRQs for RTDM are planned. The yet open design challenge is how to support driver writers best when they have to switch between both models, e.g. during compile-time (keep in mind, you also have to switch the locking: spinlock<->mutex).
