It depends on what is passed to "blockdev_alloc(name, major, minor)"
(siplified, whatever the exact function name is). And of course every block
driver is free to pick any value of "name". If its already taken it gets
-EBUSY.

My point is that the "hd" code is not only connected to IDE hardware, but also
to the xen frontend driver. Is it difficult to restore and maintain that
removed code for upcoming releases?
