In the patch, I introduce a new page system -- pps which can improve
Linux swap subsystem performance, you can find a new document in
Documentation/vm_pps.txt. In brief, swap subsystem should scan/reclaim
pages on VMA instead of zone::active list ...
The early swap subsystem was really scan/reclaim based on mm/vma,
but now it changes to pages on active/inactive list. Perhaps you are
not following a right direction.
