From 62a1391ddd6fbe82fc02154dc760bcc5cbc9ef68 Mon Sep 17 00:00:00 2001 From: Haibo Liu Date: Mon, 9 Jul 2012 16:29:28 -0400 Subject: [PATCH] ext4: remove an unused statement in ext4_mb_get_buddy_page_lock() In this patch, the statement "poff = block % blocks_per_page" in ext4_mb_get_buddy_page_lock has no effect. It will be optimized out by the compiler, but it's better to remove it.
