Hi,

is there a generic equivalent to something like sync() in Linux or do you
loop through block handles and issue
disconnectcontroller()/connectcontroller() or do the exclusive open then
connectcontroller().


Also in general, what is the difference between a "ControllerHandle" and a
"DriverHandle" in terms of getting handles.  In other words, If I have a
block io protocol handle is that a controller handle or a driver handle or
some other handle?   If you had a end-device like a hd, how would you get
the controller's handle (what protocol do you locate for the parent for a
controller) ???
