kompilacja supermount

Hej! Ściągnąłem sobie supermounta, próbuję skompilować i:

make[3]: Entering directory `/usr/src/linux/fs/supermount'

Oczywiście w menuconfig zaznaczyłem supermounta jako moduł. Co oznacza 
ten błąd? Przeczytałem README ale tam nic nie ma na ten temat. Tego 
stringu MEDIA_LOCK nie ma w całym jądrze...
