[PATCH 3.14 35/37] vmscan: reclaim_clean_pages_from_list() must use mod_zone_page_state()

[Greg Kroah-Hartman]

3.14-stable review patch.  If anyone has any objections, please let me know.

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

From: Christoph Lameter <cl@xxxxxxxxx>

commit 83da7510058736c09a14b9c17ec7d851940a4332 upstream.

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