  Modified files:
    sys/kern             subr_devstat.c 
  Log:
  If devstat_new_entry() is passed a unit number of -1 assume that
  the devstat is for an "interior" GEOM node and register using the
  name argument as a geom identity pointer.  Do not put these devstat
  structures on the list returned by the sysctl.
  
  This gives us the ability to tell the two kinds of nodes apart and
  leave the current "strictly physical" view of devstat intact without
  modifications, yet be able to use devstat for both kinds of devices.
  
  It also saves us bloating struct devstat with another 48 bytes of
  space for the name.  At least for now.
