    SubjectRe: [RFC] respect the referenced bit of KVM guest pages?
    Side question -
    Is there a good reason for this to be in shrink_active_list()
    as opposed to __isolate_lru_page?

    if (unlikely(!page_evictable(page, NULL))) {
    putback_lru_page(page);
    continue;
    }

    Maybe we want to minimize the amount of code under the lru lock or
    avoid duplicate logic in the isolate_page functions.

    But if there are important mlock-heavy workloads, this could make the
    scan come up empty, or at least emptier than we might like.
