Glad to hear it! If you want to review my PR where I change the type, it
is here: https://github.com/tianocore/edk2/pull/6381. It is a large PR
to bring in the dynamic stack cookies, too, I can split it into two if
desired (waiting to hear back from Mike Kinney on whether he wants it in
two).

Thanks,
Oliver
