Hi all,

Because qemu uses strtoll to parse string in parse_str function of 
qapi/string-input-visitor.c,  I'd like to know why the parameters of 
scsi-hd device which are specified as uint64(says wwn) are getting 
interpreted as signed long int's instead

e.g:
# qemu-system-x86_64 -device scsi-hd,?
......
scsi-hd.wwn=uint64
......

Does the highest bit of wwn value have special meaning and it must be a 
zero?

Thanks in advance,
Lin
