Take a filesystem for example. They can be built as a module, and still be used by the kernel. In this case that's basically done by function pointers. When the fs module is loaded it registers itself to the kernel and passes pointers to the basic operations to the kernel. The kernel itself doesn't contain any calls to (for example) fat_statfs. That's only used in the fat module. The kernel calls the statfs function pointer in the super_operations struct the fat module registered when it was loaded. Kristof
