Xue jiufei 0e048316ff ocfs2: check existence of old dentry in ocfs2_link() ... System call linkat first calls user_path_at(), check the existence of old dentry, and then calls vfs_link()->ocfs2_link() to do the actual work. There may exist a race when Node A create a hard link for file while node B rm it. Node A Node B user_path_at() ->ocfs2_lookup(), find old dentry exist rm file, add inode say inodeA to orphan_dir call ocfs2_link(),create a hard link for inodeA. rm the link, add inodeA to orphan_dir again When orphan_scan work start, it calls ocfs2_queue_orphans() to do the main work. It first tranverses entrys in orphan_dir, linking all inodes in this orphan_dir to a list look like this: inodeA->inodeB->...->inodeA When tranvering this list, it will fall into loop, calling iput() again and again. And finally trigger BUG_ON(inode->i_state & I_CLEAR).
