The InnoDB source code contains quite a few references to a closed-source hot backup tool which was originally called InnoDB Hot Backup (ibbackup) and later incorporated in MySQL Enterprise Backup. The open source backup tool XtraBackup uses the full database for recovery. So, the references to UNIV_HOTBACKUP are only cluttering the source code.
