I understand and agree with most of what you wrote. I think we still have the mprotect()/UFFDIO_WRITE(un)PROTECT issue, which I either do not understand your position or disagree with it. :) Anyhow, instead of too many words, I’ll send v2 based on your feedback, which would help to refine the behavior and clear any misunderstanding we might have.
