Message-Id: <1295896699-7314-1-git-send-email-bosong.ly@taobao.com> Date: Tue, 25 Jan 2011 03:18:19 +0800 From: Coly Li <colyli@...il.com> To: linux-ext4@...r.kernel.org Cc: Coly Li <bosong.ly@...bao.com> Subject: [PATCH] __ext4_get_inode_loc: use s_inodes_per_block directly From: Coly Li <bosong.ly@...bao.com> In __ext4_get_inode_loc(), inodes_per_block is calculated by (EXT4_BLOCK_SIZE(sb) / EXT4_INODE_SIZE(sb)). This is unncessary, the value can be found directly from s_inodes_per_block.
