Subject [GitHub] flink issue #5381: [FLINK-8523][network] Stop assigning floating buffers for...

    https://github.com/apache/flink/pull/5381
  
    There is one issue I am thinking. 
    After the input channel is unblocked, we can check whether this input channel needs request
floating buffer from pool (if `availableNum < numRequiredBuffers` and `!isWaitingForFloatingBuffers`).
Otherwise the request will be triggered by `onSenderBacklog` next time.
    What do you think is better?
