calling memcpy immediately after memset with the same region of memory
makes memset redundant.

Thanks for the patch, it looks good. You don't need to say that it
builds successfully, because we already assume that's true.

Sometimes I put a comment here under the cut off line if I want people
to know that I haven't tested a patch.
Anyway, don't resend the patch. It's fine as-is (unless Greg
complains) but it's just for future reference.
