In ext4_orphan_cleanup(), if ext4_truncate() failed to get a transaction handle, it didn't remove the inode from the in-core orphan list, which may probably trigger below error dump in ext4_destroy_inode() during the final iput() and could lead to memory corruption on the later orphan list changes.
