something like this:
- #define SetPageReferenced(page) set_bit(PG_referenced, &(page)->flags) + #define SetPageReferenced(page) \ + if (!test_bit(PG_referenced), &(page)->flags) \ + set_bit(PG_referenced, &(page)->flags) On some platforms all the {test_,}{clear,change,set}_bit() ops give you this cache behavior. How hard would it be to make ix86 act similarly? - 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/
