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
