I'm also not concerned because the cost is linear with the amount of memory (and the cost has an high bound, that is the size of the lower zones, so it's not like the struct page that is a percentage of ram guaranteed to be lost) so it's generally not noticeable at runtime, and it's most important in the big systems (where in turn the cost is higher). - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
