Hi,

these patches make the workingset code cgroup-aware, so that page
reclaim works properly when using the cgroup memory controller. More
details in the 5/5 changelog.

This should have been part of the original thrash detection patches,
but those were already too complex. So here we go.

Thanks,
Johannes
