Alan,
I included fastwalk patch because I thought it was a stable and very useful optimisation. Even for 2.4. (I was expecting comments/flames on it when I first included it.
Now if you think it is a 2.5 thing and can cause any potential problem for 2.4 I will remove it. - 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/
