LRU Acive Pages

["Bithika Khargharia" <bithika@xxxxxxxxx>]

Hi All,

This may be an over-simplification.

 If the total number of active pages (for all zones) is X at any instant of time, does it mean that memory activity at that instant <= (X * pg_size) kBytes?

I know that the zone active lists only keep track of user-level active pages. So does (X * pg_size) kBytes indicate instantaneous user-level memory usage? Is there any other way of getting the instantaneous system total memory usage?

Thanks
Bithika
