    Subject[PATCH 3.14 35/37] vmscan: reclaim_clean_pages_from_list() must use mod_zone_page_state()
    Date
    3.14-stable review patch.  If anyone has any objections, please let me know.

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

    From: Christoph Lameter <cl@linux.com>

    commit 83da7510058736c09a14b9c17ec7d851940a4332 upstream.

    Seems to be called with preemption enabled. Therefore it must use
    mod_zone_page_state instead.
