Checking up on this conversation. The intended use case has nothing to 
do with RNG - we merely need a notification for system level user space 
that a system clone operation happened so it can act on it.

Please consider taking the patch as is or advise on how to proceed to 
address this non-RNG use case.


Thanks,
