Thank you very much for the patch!

I don't see an assignment on file for you for "GLIBC."

Just for clarity...

Could you please confirm that you would like to submit this patch
under the exception for copyright relevance?

That is to say that these changes can't really be copyrighted
and that they are below the 15 line exemption even if they were.
