unsigned, yet we assign it -1?
Yeah, that's how the block layer does internally, too.
Maybe we should export SCSI_NO_TAG and use it here.
I think it's better that the LLDD would not have to deal with "no tag"
scenario (pm8001 driver has to handle it in this series). Rather libsas
can handle that, and fail an allocation of a slow_task to the LLDD instead.
Thanks,
John
