Date: Mon, 22 Apr 2013 17:25:13 +0900 From: Joonsoo Kim <iamjoonsoo.kim@....com> To: Andrew Morton <akpm@...ux-foundation.org> Cc: linux-kernel@...r.kernel.org, linux-mm@...ck.org, Yinghai Lu <yinghai@...nel.org>, Johannes Weiner <hannes@...xchg.org>, Jiang Liu <liuj97@...il.com>, Joonsoo Kim <iamjoonsoo.kim@....com> Subject: [PATCH 2/2] mm, nobootmem: do memset() after memblock_reserve() Currently, we do memset() before reserving the area. This may not cause any problem, but it is somewhat weird. So change execution order.
