Is this really abusing? We know that a page is shaky and will likely go bad in the future, For now it is still accessible. Trying to migrate off that page stop using it right away sounds pretty logical to me. Now, the weird thing is that for hugetlb we wants a different behavior (keep using the page and ignore the request to evacuate). > >> If you think this should be handled differently, I'm open to suggestions. > > Yes, do not treat hugetlb pages any special.

I agree with that. -- Cheers, David
