HELP,
In include/asm-i386/processor.h, struct thread_struct I can add
struct list_head *mylist;
but not
struct list_head mylist;
while in both cases
#include <linux/list.h>
is being used.
I really need this, so if anyone has the solution to my problem...
Thanks in advance, Frank.

It a cross includes problem and you can declare a pointer to something
coz the pointer has a fixed size while the full struct is prohibited
because its size is unknown.

A struct list_head is about twice as large as a pointer.

Unfortunately, linux/list.h includes asm/processor.h, via linux/prefetch.h.
Making them include each other is not going to work very well.
The include files need a fairly hefty shakeup in 2.5.
