So ODX support is still low on my current TODO list, but I'm happy to assist anyone in the short-term who is willing to submit patches for implementing the first steps to get the ball rolling. IIRC, the CDB emulation additions are really quite straight-forward, especially given you've already got a working ddpt client. ;) Of course, the more interesting question is once EXTENDED_COPY(LID4) emulation is in place, how is the interface for supporting tokenized READ/WRITE through to struct block_device (and FILEIO too) going to look..? I haven't seen much discussion on this topic, and would be interested to hear if anyone has thoughts on how that piece might work. --nab -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
