                         vm_reserv.h 
  Log:
  Introduce vm_reserv_reclaim_contig().  This function is used by
  contigmalloc(9) as a last resort to steal pages from an inactive,
  partially-used superpage reservation.
  
  Rename vm_reserv_reclaim() to vm_reserv_reclaim_inactive() and
  refactor it so that a separate subroutine is responsible for breaking
  the selected reservation.  This subroutine is also used by
  vm_reserv_reclaim_contig().
