Tiap-tiap struktur data vm_area_struct mendeskripsikan suatu area memori virtual untuk sebuah proses.

struct vm_area_struct {
  struct mm_struct * vm_mm;  /* VM area parameters */
  unsigned long vm_start;
  unsigned long vm_end;
  pgprot_t vm_page_prot;
  unsigned short vm_flags;
/* AVL tree of VM areas per task, sorted by address */
  short vm_avl_height;
  struct vm_area_struct * vm_avl_left;
  struct vm_area_struct * vm_avl_right;
/* linked list of VM areas per task, sorted by address */
  struct vm_area_struct * vm_next;
/* for areas with inode, the circular list inode->i_mmap */
/* for shm areas, the circular list of attaches */
/* otherwise unused */
  struct vm_area_struct * vm_next_share;
  struct vm_area_struct * vm_prev_share;
/* more */
  struct vm_operations_struct * vm_ops;
  unsigned long vm_offset;
  struct inode * vm_inode;
  unsigned long vm_pte;      /* shared mem */
};
