From 06ee5c75b57564435933fc0ffa72dc18a2fda0e7 Mon Sep 17 00:00:00 2001 From: Joseph Qi Date: Mon, 16 Feb 2015 15:59:54 -0800 Subject: ocfs2: add functions to add and remove inode in orphan dir Add functions to add inode to orphan dir and remove inode in orphan dir. Here we do not call ocfs2_prepare_orphan_dir and ocfs2_orphan_add directly. Because append O_DIRECT will add inode to orphan two and may result in more than one orphan entry for the same inode.
