Hello Long, What bug did you encounter, with which combination of ULP (sd?) and LLD SCS= I driver(s) and for which request type (REQ_OP_*)? You will have to mention t= hat 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.=
