Both Joonsoo Kim and Minchan Kim have reported premature OOM kills.

appear to be at fault -- pgdat being considered unreclaimable prematurely

The series is in three basic parts;
Both Joonsoo Kim and Minchan Kim have reported premature OOM kills.
The common element is a zone-constrained allocation failings. Two factors
appear to be at fault -- pgdat being considered unreclaimable prematurely
and insufficient rotation of the active list.
