    From
    Date

    From: IWAMOTO Toshihiro <iwamoto@valinux.co.jp>
    > I found the tests does not work well with Dave's patchset.
    > I've found the followings:
    >
    > - setup_per_zone_pages_min() calls should be added in
    > capture_page_range() and online_pages()
    > - lru_add_drain() should be called before try_to_migrate_pages()

    The following patch deals with the first item.
