Hi David,

Thank you for your review. You raised many good points regarding optimizations here. I'll switch to using 2G as the max entry size (`SZ_2G` from `linux/sizes.h`), and remove divisions and multiplications. I'll also replace the `for()` loop with `while (length)`, and drop `min_t()` in favor of `min()` by casting `SZ_2G` to `size_t`.

You shouldn't need a cast at all.

David L.

I'll send out a v2 with these changes shortly.

Thanks, David
