Hi, thanks for talking the time out to review the patch.

I've addressed the comments you made and also fixed the build issues. It now builds cleanly again and passes all checks.

I'm not sure however on how to split the patch, as we definitely need all the pieces to pass the CI tests. I hope it isn't too much of a burden to review the patch.

Thanks.
