Well.....   we should be moving away from ioctls for this.

For addressing raid arrays, inject REQ_SPECIAL requests directly into 
the request_queue.

For addressing elements above raid array level (such as when creating 
new arrays, etc.) there should be a character device that talks to the 
host driver.

And please let's not bring that godawful SNIA API into the kernel ;-)
