Llvm-test-suite accepts merge commits


We noticed that the llvm-test-suite is configured differently than the main llvm-project repository. Specifically, it defaults to accepting PRs as merge commits (e.g. Add unit tests for Fortran's type finalization feature by rouson · Pull Request #13 · llvm/llvm-test-suite · GitHub). I don’t mind the pull requests themselves (although I think the same review policy as for llvm-project should apply), but can the configuration be changed to allow only a linear history? Thanks.

I’ve updated the config to requre linear history now.
