Thanks for doing this work Nick. I'm going to take your ideas and apply them to an ipv4 routing cache dynamic growth patch I worked on a while ago.
One minor nit:

I don't see any reason to make 'mask' an unsigned long and this makes this structure take up 8 bytes more than necessary on 64-bit. - 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/
