From 6218b90e7669d83cb8ad744f3400205d260597f2 Mon Sep 17 00:00:00 2001 From: Tao Ma <boyu.mt@taobao.com> Date: Mon, 21 Feb 2011 11:18:30 +0800 Subject: [PATCH] ocfs2: Little refactoring against ocfs2_iget. ocfs2_iget is used to get/create inode. Only iget5_locked will give us an inode = NULL. So move this check ahead of ocfs2_read_locked_inode so that we don't need to check inode before we read and unlock inode. This is also helpful for trace event(see the next patch).
