[RFC PATCH] mm/zsmalloc: remove unnecessary check
From: Mahendran Ganesh
Date: Thu Nov 20 2014 - 08:22:13 EST
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.
