It seems that clone() the syscall takes two arguments:
struct linux_clone_args {
int flags;
void *stack;
};
the wrapper in library takes care of pushing the function address and its
argument on to the stack. You probably also want to map linux clone flags
to that of rfork's: CLONE_FILES -> RFFDG, CLONE_VM -> RFMEM.
