Problem getting all vmas

["Breno" <breno@secforum.com.br>]

Hi , i tryed to get all vmas with this piece of code :


....
struct task_struct *task = find_task_by_pid();
struct vm_area_struct *vma,*next;

vma = task->mm->mmap;

while(vma)
{
     next = vma->vm_next;
    my_function();
    ....
    vma = next;
 }

but when i do insmod procm.o ... the program seems to enter in an infinite
loop.
Am I getting all vmas with this while() ?

thanks
