Summary: When internal cpp modernizer attempts to format rocksdb code, it will replace macro `ROCKSDB_NAMESPACE` with its default definition `rocksdb` when collapsing nested namespace. We filed a feedback for the tool T180254030 and the team filed a bug for this: https://github.com/llvm/llvm-project/issues/83452. At the same time, they suggested us to run the modernizer tool ourselves so future auto codemod attempts will be smaller. This diff contains: Running `xplat/scripts/codemod_service/cpp_modernizer.sh` in fbcode/internal_repo_rocksdb/repo (excluding some directories in utilities/transactions/lock/range/range_tree/lib that has a non meta copyright comment) without swapping out the namespace macro `ROCKSDB_NAMESPACE` Followed by RocksDB's own `make format` Pull Request resolved: https://github.com/facebook/rocksdb/pull/12398 Test Plan: Auto tests Reviewed By: hx235 Differential Revision: D54382532 Pulled By: jowlyzhang fbshipit-source-id: e7d5b40f9b113b60e5a503558c181f080b9d02fa
