hmm, it effectively is if there is no other policy set. The changelog is a bit misleading. In V3, this will be dropped entirely. It was not clear that doing a remote alloc for home nodes was a good idea. Instead memory is always allocated locally to the faulting process as normal and migrated later if necessary. -- Mel Gorman SUSE Labs -- 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/
