Yes, if send-with-invalidate causes a sync-tpt which applies only to the 
specific rkey (I assume its documented in the PRM) this can be used to 
make the mellanox fmrs --much-- more secure.  Are you thinking on 
enhancement to support that for consumers that use FMRs through the pool 
at the core?

Or.
