Hello, Johannes.

Ccing Vlastimil, because this patch causes some regression on
stress-highalloc test in mmtests and he is a expert on compaction
and would have interest on it. :)

Thanks. It's not the first case when stress-highalloc indicated a regression due to changes in reclaim, and some (not really related) change to compaction code undid the apparent regression. But one has to keep in mind that the benchmark is far from perfect. Thanks for the investigation though.
