-- a2adbf75201f6b7feba929f77dfc4f87f9c1110b by Abseil Team <absl-team@google.com>: This change allows for capturing the address of the mutex from which a call to `Block(...)` could be introducing latency. The attribute is a no-op if the application is not being built with XRay instrumentation. See http://llvm.org/docs/XRay.html for more information about XRay.
