                        This is an obsolete manual section.  Once
                        it was thought a good  idea  to  document
                        the  Linux  kernel here, but in fact very
                        little has been documented, and the docu-
                        mentation   that   exists   is   outdated
                        already.  There  are  better  sources  of
                        information for kernel developers.
