Andrew,

I managed to back this patchset with two test cases :)

They demonstrated that
- X desktop responsiveness can be *doubled* under high memory/swap pressure
- it can almost stop major faults when the active file list is slowly scanned
  because of undergoing partially cache hot streaming IO

The details are included in the changelog.

Thanks,
Fengguang
