  "message": "Track maximum wait duration across all woken waiters in Mutex::UnlockSlow.\n\nWhen waking a batch of readers, `UnlockSlow` resets `contention_start_cycles` on each woken waiter, and any waiter that fails to acquire the lock is requeued in LIFO order at the front of the wait list. Recording `max_wait_cycles` from only the first waiter in `wake_list` therefore captures the shortest recent wait of a requeued reader rather than the longest wait in the woken batch. Compute the maximum across all woken non-condition waiters instead.\n\nPiperOrigin-RevId: 1010591185\n",
