I didn't use SCSI_NO_TAG because it seemed to relate to the int tag member in struct request and not the unsigned char tag member in struct scsi_cmnd. In light of the plan to remove the tag member from struct scsi_cmnd, I don't know what to do with this patch. It doesn't really help with that plan so I figured it would be NAK'd. I haven't given any thought to the problem of converting drivers to block layer tags (which might involve SCSI_NO_TAG, I guess). I have too much other work in progress. That's why I suggested commenting out #define SUPPORT_TAGS until they could be converted. -- -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
