Hi everybody,
I have created a new syscall which I've included in the mm directory but I have some problems when compiling it.
In my syscall I use routines that have the source code on memory.c, so, in my .c file I define them like this
extern void establish_pte(struct vm_area_struct *,unsigned long,pte_t *,pte_t);
extern int do_wp_page(struct mm_struct *,struct vm_area_struct *,unsigned long,pte_t *,pte_t);
extern int do_no_page(struct mm_struct *,struct vm_area_struct *,unsigned long,int,pte_t *);
In order to indicate to the compiler that they are coded in an another file, but when I compile my kernel by doing make bzImage I got three errors saying that there are references to this routines are not defined.
Does anybody have some idea about what I'm doing wrong?
I've obtained the instructions to add a new syscall from that link http://www.mathcs.carleton.edu/faculty/jondich/courses/cs307_s02/documents/syscall.html
Thanks in advance, Cristina.
