@tstellar Strangely, `pr-subscribers-clang-driver` is not added for this PR.

```
% echo '/clang/*/Driver/' >> .gitignore
% git check-ignore -v --no-index clang/lib/Driver/Driver.cpp
.gitignore:74:/clang/*/Driver/  clang/lib/Driver/Driver.cpp
% git restore .gitignore
```

We can see that the pattern in `.github/CODEOWNERS` can match clang/lib/Driver/ files.
