Can it be so simple? Why previous versions takes care of holding "(void)*1"
and "(void)*2" then? Could you elaborate?  

"1" means printing "Personalities", which is now moved to md_seq_start,
and "2" means printing "unsed devices" which is now moved to
md_seq_stop. And now md_seq_next is only used to iterate the mddev list.

Ok, LGTM.
