    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?
