By now mutexes are used by io subsystem:
All input/output requests (iors) and queues of iors are guarded by spin mutexes.
As for devices, their NewBus sided structures will be guarded by
(spin?) mutexes.

I don't really get what you mean. Did that answer about NewBus sided
structures + paralleled/serialized ior processing clarify anything?
