Yes so it needed fixing and without all the kref, kmalloc, unique object
structure per ide driver code spew too.

I consider that a technical fact. The last IDE code I maintained fully
in 2.4 had mostly working locking, drive hotplug, open for unbound
drivers, didnt oops on spurious irqs and wasn't losing all sorts of
useful boot options. I had hoped that I wouldnt have to totally fork the
2.6 IDE code in order to get back to where 2.4-ac was and get the
locking working so you can't oops it via /proc
