   Hi,

The attached patch sets the error field in the statically allocated 
frontend and backend bus structs.  This is needed to make sure nobody 
ever tries to use them uninitialized.  Without that patch you can kill 
your machine by trying to load xen-vnif or xen-vblk on native hardware.

please apply,

   Gerd
