tail.Config ReOpen abnormal

  
    seek := &tail.SeekInfo{}
    seek.Offset = 0
    seek.Whence = os.SEEK_END

    config := tail.Config{}
    config.Follow = true
    //config.ReOpen = true
    config.Location = seek

    tails, err := tail.TailFile(filename, config)

When I stop using ReOpen，I got as below：

Stopping tail as file no longer exists: my.log
