Been talking among ourselves here and for this patch and the other one 
we can just rely on the standard CONFIG_FAULT_INJECTION. I will resubmit 
those with my next set of patches.

In the future though it may be nice rather than having a single debug 
variable, but a small set of them that are used stack wide. So no mlx or 
hfi1, etc specific ones, but just for instance a general reference 
counting flag for mrs and qps. If we come up with some small sane list 
that we can all agree on would that be acceptable? Yeah we are growing 
the kconfig but it's at least controlled and thought out.
