    SubjectRe: [RFC] Track mlock()ed pages

    I think it is not quite right. You are tracking the number of ptes
    that point to mlocked pages, which can be >= the actual number of pages.

    Also, page_add_anon_rmap still needs to be balanced with page_remove_rmap.

    I can't think of an easy way to do this without per-page state. ie.
    another page flag.
