memfd_create() seems to bring a fair amount of baggage along (the fd part :) if all we want is a marker. Really, all we need is _a_ bit, and some way to plumb to userspace the RSS values of VMAs with that bit set. Creating and mmap()'ing a fd seems a rather roundabout way to get there. -- 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/
