i don't think that will make much difference, i was more wondering about the cost of an (additional) pointer dereference in a hot-path. i think most modern x86 CPUs have pretty decent speculation logic so the load won't usually cause horrible stalls whereas for some other some other CPUs this isn't the case
of course w/o measurements this is just wild speculation - 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/
