Great.

The new patch still has a "src" output, even though it does not seem to
use it.

Nice job on the comment.  :-)

Looks like I missed a couple of things in the first round, sorry about
that.  Here it comes...

Use the "11.2.0" tag here instead of the commit hash.

Can you add a comment about where you got that version number from?
Also, would it make sense to package this separately?  Can be done later

Apart from these minor issues, I think it's good to go.  \o/

Can you send an updated patch?  TIA!  :-)
