There's not much point updating it to current coding style, deleting fs/efs is probably the best option. The EFS name is common for several filesystems, not to be confused with eg. Encrypted File System. In linux it's the IRIX version, check Kconfig, and you could hardly find the utilities to create such filesystem.
