    Subject[PATCH 3.12 115/144] mm/mempolicy: correct putback method for isolate pages if failed
    Date
    3.12-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Joonsoo Kim <iamjoonsoo.kim@lge.com>

    commit b0e5fd7359f1ce8db4ccb862b3aa80d2f2cbf4d0 upstream.

    queue_pages_range() isolates hugetlbfs pages and putback_lru_pages()
    can't handle these. We should change it to putback_movable_pages().

    Naoya said that it is worth going into stable, because it can break
    in-use hugepage list.
