Hi, we are making some changes to the notification system, could you move these paths lists into [.github/new-prs-labeler.yml](https://github.com/llvm/llvm-project/blob/main/.github/new-prs-labeler.yml).  Use llvm:inliner for the label name in the file e.g.
```
llvm:inliner:
  - /path/1
  - /path2/
```
Also note that this new file uses [minimatch](https://github.com/isaacs/minimatch) glob parser which is different in some ways from the .gitignore syntax used by the CODEOWNERS file.  The main difference is you need to do things like directory/** instead of directory/ to select a directory's contents.
