 The last change was the "cnt" structure rename; the previous rev was the =
 
 one where freepages was set to cnt.v_free_target (the margin was removed =
 
 in the rev sent on 24-March in the morning) -- there was no logic change =
 
 made in the 26th March followup .vs. the previous one from 24 March.
