The Sub channel event callback is threaded using workqueues.
The work uses the FSM introducing the VFIO_CCW_EVENT_SCH_EVENT
event.
I don't think this is a good name; after all, all of the events are
events for the subchannel :)
This seems to be more of a "we need to update the schib" event...
VFIO_CCW_EVENT_SCHIB_CHANGED? _SCH_CHANGED? _UPDATE_NEEDED?
Tbh, I'm not quite sure this makes sense for me yet... will continue
reading, but this probably needs a 'why'.
SCHIB_CHANGED or something like this sounds better indeed. :)
The update of the SCHIB is now done inside the FSM function.
