Using the control device is usefull if you want to react on messages from
the control interface without the need to open virtual devices at that
or keep filehandles open all the time.
Userspace recovery of failed multipath devices has to save as much memory
since it must pin itself into memory in order to handle low-mem
So I would like to see a interface through the control device as well.
