FWIW, I saw nothing of major concern while reading through the series other
than the delete-lumpy-reclaim portion. I've posted a series that should
address both the lumpy reclaim concerns while also improving the performance
of compaction in general.

For the rest of the series, the vast majority of my comments were nits as
my questions were covered (and addressed) in previous revisions. I'll try
and set time aside to convert some of the libhugetlbfs-orientated to run
against these patches but I'm not anticipating any problems and it'd be
nice to see merged at some point.
