Anton's patch may be small, but that's just the tiny > fixup patch to Peter's much scarier one ;) Right, so we can either merge my scary patches now and have 3.0 boot on 16+ node machines (and risk breaking something), or delay them until 3.0.1 and have 16+ node machines suffer a little. The alternative quick hack is simply to disable the node domain, but that'll be detrimental to regular machines in that the top domain used to have NODE sd_flags will now have ALL_NODE sd_flags which are much less aggressive. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
