    reasoning behind the three cases though:

    + if (pte_file(*pte))
    + present = mincore_linear_page(vma, pte_to_pgoff(*pte));

    + present = pte_present(*pte);
    + else
    + present = mincore_linear_page(vma, pgoff);

    Could you explain the logic behind each of these? Perhaps with permanent
