Okay, thanks.

Another question about the original patches: did you test that a 64-bit
backend can communicate with 32-bit frontend (and vice versa)? Either you
need to make sure that all the shared-memory structures defined in vscsiif.h
compile identically for 32-bit and 64-bit mode, or you need to detect the
frontend's 'bitness' in scsiback and optionally do 32-to-64 or 64-to-32
conversion. I think it's obvious which is less hassle. ;-)

Handling this is really a prerequisite for putting these patches into a
stable Xen release.
