Two notes:

1) Why are you rebasing the tree right before sending it? There
   should be zero need to do that, please don't.

2) Please switch to https://patch.msgid.link/ for you Link tags,
   if they are just links to the patch submission. That makes it
   clear this is the case, just the patch. You can use lore for
   actual bug reports etc.

Pulled, but please change the above two things going forward.
