Date: Thu, 20 Nov 2014 21:21:56 +0800 From: Mahendran Ganesh <opensource.ganesh@...il.com> To: minchan@...nel.org, ngupta@...are.org, iamjoonsoo.kim@....com Cc: linux-mm@...ck.org, linux-kernel@...r.kernel.org, Mahendran Ganesh <opensource.ganesh@...il.com> Subject: [RFC PATCH] mm/zsmalloc: remove unnecessary check ZS_SIZE_CLASSES is calc by: ((ZS_MAX_ALLOC_SIZE - ZS_MIN_ALLOC_SIZE) / ZS_SIZE_CLASS_DELTA + 1) So when i is in [0, ZS_SIZE_CLASSES - 1), the size: size = ZS_MIN_ALLOC_SIZE + i * ZS_SIZE_CLASS_DELTA will not be greater than ZS_MAX_ALLOC_SIZE This patch removes the unnecessary check.
