    Memory controller: make page_referenced() cgroup aware · bed7161a
    Balbir Singh 提交于
    Make page_referenced() cgroup aware.  Without this patch, page_referenced()
    can cause a page to be skipped while reclaiming pages.  This patch ensures
    that other cgroups do not hold pages in a particular cgroup hostage.  It
    is required to ensure that shared pages are freed from a cgroup when they
    are not actively referenced from the cgroup that brought them in
