in shrink_active_list()")
In the interest of keeping my fingers from the flames at LSF/MM, I'm
releasing an RFC for lumpy reclaim removal.
I grabbed them, thanks.
I do have a concern with this: I was expecting lumpy reclaim to be
replaced by compaction, and indeed it is when CONFIG_COMPACTION=y.
But when CONFIG_COMPACTION is not set, we're back to 2.6.22 in
relying upon blind chance to provide order>0 pages.
Is this an issue for any architecture?
I could see NOMMU being unable to use compaction, but
chances are lumpy reclaim would be sufficient for that
configuration, anyway...
