URL: https://github.com/llvm/llvm-project/commit/e886ba1d5971ddb3b9242f7300cc97646670e9ce DIFF: https://github.com/llvm/llvm-project/commit/e886ba1d5971ddb3b9242f7300cc97646670e9ce.diff LOG: [debugserver] Migrate RNBRemote away from PThreadMutex (NFC) (#137547) The debugserver code predates modern C++, but with C++11 and later there's no need to have something like PThreadMutex. This migrates RNBRemote away from PThreadMutex in preparation for removing it.
