Sounds like a good idea. Like Hannes I have several patches
that haven't been rejected but seem to have been lost in
the process:
   - expand the SG_SCSI_RESET ioctl() to include non reset
     escalating variants
   - permit the sg driver to accept SCSI cdbs greater than
     16 bytes long (bsg already can)

Also I have done some work in sg3_utils to support 64 bit
LUNs in Linux. That work assumes the solution proposed by Hannes.
