I'd say it's unreasonable to assume that all pages in all cases are likely to be cache-hot. Example: what if the pages are being truncated and were found to be on the inactive LRU, unreferenced? A useful exercise would be to go through all those pagevec_init() sites and convince ourselves that the decision at each place was the correct one. -- 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/
