SANE-SENSE Support in scsi usb transport


Feature to truncate user sense buffer was added in the following patch:
http://marc.info/?l=linux-usb&m=123135651222832

There is a possibility of user application misinterpreting it as a driver bug as scsi standard or SAT spec do not mention this behavior.

I would like to ask the experts about the advantages of this feature for user level applications? If user buffer is capable of holding complete buffer as returned by device, why can't we just fill the complete buffer as it is instead of truncating the buffer length?
