Subject: [PATCH] zsmalloc: fixup trivial zs size classes value in comments
Date: Thu, 15 May 2014 16:38:31 +0800 [thread overview]
Message-ID: <000201cf7019$3e2c7cf0$ba8576d0$%yang@samsung.com> (raw)
According to calculation, ZS_SIZE_CLASSES value is 255
on systems with 4K page size, not 254. The old value may
forget count the ZS_MIN_ALLOC_SIZE in.
This patch fixup this trivial issue in the comments.
