Message-id: <1359973626-3900-1-git-send-email-m.szyprowski@samsung.com> Date: Mon, 04 Feb 2013 11:27:05 +0100 From: Marek Szyprowski <m.szyprowski@...sung.com> To: linux-mm@...ck.org, linux-kernel@...r.kernel.org Cc: m.szyprowski@...sung.com, akpm@...ux-foundation.org, minchan@...nel.org, mgorman@...e.de, kyungmin.park@...sung.com Subject: [PATCH] mm: cma: fix accounting of CMA pages placed in high memory The total number of low memory pages is determined as totalram_pages - totalhigh_pages, so without this patch all CMA pageblocks placed in highmem were accounted to low memory.
