Can we omit the whole defer_meminit= thing and permanently enable the feature? That's simpler, provides better test coverage and is, we hope, faster. And can this be used on non-NUMA? Presumably that won't speed things up any if we're bandwidth limited but again it's simpler and provides better coverage. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
