copying linked lists structs to kernelland

Hi,

How do I copy best a data structure which contains two or more linked 
list heads (a la linux/list.h) plus
some other fields to kernelland?
Obviously a simple copy_from_user(new_struct,  (struct my_struct*) data, 
sizeof(struct my_struct)).. does
not work.

Thanks for your help,
jonathan heusser
