Sounds great.

> If you still have a spinlock in the primary handler, wouldn't that sleep in a non-sleepable context? Forgive my -rt ignorance, but I understood that in -rt, all the spinlock go to sleep which basically mean that we can't take any spinlock in the primary irq handler so I am a bit confused here.

After my change there is no primary handler anymore, just the threaded
where you can take the (sleeping) spinlock.
Everything what you wrote is correct:
- you can't take a spinlock in the primary handler
- all spinlocks may sleep
