The patch titled Subject: ocfs2: should add inode into orphan dir after updating entry in ocfs2_rename() has been removed from the -mm tree. Its filename was ocfs2-should-add-inode-into-orphan-dir-after-updating-entry-in-ocfs2_rename.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: alex chen <alex.chen@xxxxxxxxxx> Subject: ocfs2: should add inode into orphan dir after updating entry in ocfs2_rename() There are two files a and b in dir /mnt/ocfs2. node A node B mv a b In ocfs2_rename(), after calling ocfs2_orphan_add(), the inode of file b will be added into orphan dir. If ocfs2_update_entry() fails, ocfs2_rename return error and mv operation fails. But file b still exists in the parent dir. ocfs2_queue_orphan_scan -> ocfs2_queue_recovery_completion -> ocfs2_complete_recovery -> ocfs2_recover_orphans The inode of the file b will be put with iput(). ocfs2_evict_inode -> ocfs2_delete_inode -> ocfs2_wipe_inode -> ocfs2_remove_inode OCFS2_VALID_FL in the inode i_flags will be cleared. The file b still can be accessed on node B. ls /mnt/ocfs2 When first read the file b with ocfs2_read_inode_block(). It will validate the inode using ocfs2_validate_inode_block(). Because OCFS2_VALID_FL not set in the inode i_flags, so the file system will be readonly. So we should add inode into orphan dir after updating entry in ocfs2_rename().
