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. > > Once all the issues are believed to be settled, please send fresh shiny new > patches against latest -linus or, if there is colliding stuff in -mm, > against latest -mm.
