Fixed patch comment.
-Kame
==
constrained_alloc(), which is called to detect where oom is from,
checks passed zone_list().
If zone_list doesn't include all nodes, it thinks oom is from mempolicy.
But there is memory-less-node. memory-less-node's zones are never included in
zonelist[].
contstrained_alloc() should get memory_less_node into count.
Otherwise, it always thinks 'oom is from mempolicy'.
This means that current process dies at any time. This patch fix it.
