It is never read. Setting it and the request tag seems dodgy

This is done because there is code in the SCSI error handler that may
allocate a SCSI command without allocating a tag. See also
scsi_ioctl_reset().
Right, so we just get a loan of the tag of a real request. fnic driver

Yes. Hannes had a great series to stop passing the pointless scsi_cmnd
to the reset methods. Hannes, any chance you coul look into
resurrecting that?
Sure.
The latest iteration of that series - at v7 - still passed that fake
SCSI command to the reset method, and the reset method allocated the
internal command.
So will we change change scsi_ioctl_reset() to allocate an internal
command, rather than the LLDD?
Thanks,
