Our current transformation routine scsilun_to_int is bijective as long
as the original scsi_lun doesn't overrun 32 bits (which it might well do
one day).
Why can't you simply do this by transforming back the lun?
In general, I'm not in favour of adding redundant information to the
device structure, so if you can demonstrate we overrun our allotted 32
bits, the solution is probably to take lun up to u64 and still do the
back transform (the alternative being to substitute lun with it's
structural equivalen which would entail a lot of pain throught the SCSI
subsytem).
