Hi,
Currently linux scsi subsystem doesnt store the 8-byte luns which are
recieved in REPORT_LUNS reply. This information is forver lost once
the scan is over. In my LDD I need this information. Currently I have
to snoop REPORT_LUNS reply, do scsilun_to_int for all the luns and
store this mapping somewhere. This can be simplified by storing it in
scsi_device. This field will be meaningful only if sdev->scsi_level >=
SCSI_3.
Heres the patch
