hm, At least major two zone reclaim developer disagree my patch. Thus I have to agree with you, because I really don't hope to ignore other developer's opnion.
So, as far as I understand, the conclusion of this thread are - Drop my patch - instead, implement improvement patch of (may_unmap && page_mapped()) case - the documentation should be changed - it's my homework(?)
Can you agree this?
