I think that Christoph suggested elsewhere that we should poison all
the scsi_cmnd
I had overlooked that comment. I will look into this.
If anyone comes up with a good approach for poisoning the scsi_cmnd I
will look into this. Only overwriting struct scsi_cmnd is not acceptable
since that would result in a memory leak. See also the memory allocation
statements in scsi_mq_init_request().
Thanks,
Bart.
