I was referring to the patch that Anton Blanchard started, and I
reworked that distributes huge pages evenly over populated nodes in the
presence of nodes with no memory in the zone from which HUGEPAGES are
allocated.  You had asked [off list, last week, 17may] whether we're
still waiting for test results, to which I replied, "yes".

Later, Nish asked me for a version of the patch rebased against 22-rc2
because he was having difficulty building 22-rc*-mm* on his platform.

In this exchange, Nish is referring to his patch to allow explicit, per
node, specification of nr_hugepages via a sysfs attribute.

Will do.
