Thanks, and sorry for the hassle. But I would still like the maintainers 
to have a look, as I was curious about current usage of scsi_cmnd.tag in 
that driver.

That driver does not even compile with DEBUG_QLA1280 set beforehand. 
I'll fix that up and send as separate patches in case you want to 
shuffle the tag patch in earlier, which is prob not worth the effort.

I've done a good few more x86 randconfigs and tried to audit the code 
for more references, so hopefully that's the last.

Thanks
