Hi Damien,

What I'm wondering about is how the SCSI core should support residual
overflow. Should a new member be introduced in struct scsi_request?
Should resid_len be changed from unsigned int to int or should we
perhaps follow yet another approach?

Please introduce a new member to hold any overflow value.
And document where it is needed.

Cheers,

Hannes
