    Tells us how many pages were reclaimed by kswapd.
    
    The `pgsteal' statistic tells us how many pages were reclaimed
    altogether.  So
    
    	kswapd_steal - pgsteal
    
    is the number of pages which were directly reclaimed by page allocating
    processes.
    
    
    Also, the `pgscan' data is currently counting the number of pages
    scanned in shrink_cache() plus the number of pages scanned in
    refill_inactive_zone().  These are rather separate concepts, so I
    created the new `pgrefill' counter for refill_inactive_zone().
    `pgscan' is now just the number of pages scanned in shrink_cache().
