Date: Fri, 22 Jun 2012 02:31:06 +0800 From: Haibo <haiboliu6@...il.com> To: linux-ext4@...r.kernel.org Cc: Haibo Liu <HaiboLiu6@...i.com>, Haibo Liu <HaiboLiu6@...il.com> Subject: [PATCH][v2] ext4: delete a no useful sentence From: Haibo Liu <HaiboLiu6@...i.com> In this patch, the sentence "poff = block % blocks_per_page" in ext4_mb_get_buddy_page_lock has no effect. So we should delete it to save cpu. v1->v2: update the patch subject and the patch comment.
