one can
eventually run into a situation where the recnt can be see in
/sys/module/scsi_debug/refcnt as 0 and yet rmmod can fail.

This is not possible with linux-next.
This is false, the failure rate is just lower with linux-next, I see it
around 1/1642 tries. I'll work on a reproducer but that is a separate issue,
a generic module issue which I'll address.
I am tracking those failures and proposed fixes on korg#214015
