The callers of this have also changed - it is no longer called directly by update_load_avg(), rather via cfs_rq_util_change() from several other locations (I believe it was my patch that failed to update this comment). Could this be replaced with a more generic statement such as "called by CFS in various paths?" thanks, Steve
