My disk is a _lot_ more quiet than it used to be... This
patch didn't have the you-can-push-linux-further effect
I had hoped for, but it makes Linux a lot quieter under
the same load.
Actually, I was planning on a complete revamp of the
scan-by-VMA algorithm in mm/vmscan.c, beginning with
the removal of AGE_CLUSTER_FRACT, but maybe it works
now :-)
