I'd like to use this ABI change and introduce/expose also the ib_modify_cq verb to user space. Basically, the related patches should be quite simple (uverbs, libibverbs, libmlx4), still, I'll be glad if you tell/coach me against what code base to do that. One more thing I'd like to add to libibverbs and some device driver libraries is send-with-invalidate, but this is only user space patch set without any kernel/user, lib/app ABI change, correct?
