Hello Long,

What bug did you encounter, with which combination of ULP (sd?) and LLD SCSI
driver(s) and for which request type (REQ_OP_*)? You will have to mention that
information in the patch description anyway if you want your patch to get
accepted.

If the bug that you encountered only occurs with a single LLD, would it be
possible to implement a fix by modifying the LLD instead of the SCSI core?

Thanks,

Bart.
