I was trying to use scsi_get_lba to get the lba associated with a particular scsi_cmnd. I am able to get proper values when I send I/O through dd or FS. But when I use the sg interface either sg_dd or sg_raw the value I am getting through scsi_get_lba is not matching with the one in the CDB. Do we need to have some change in sg module for handling this, or is there anything wrong in the way I access the scsi_get_lba or sending command through sg? Any suggestion or help is highly appreciated.
