Fix it, then Ship it!





src/slave/containerizer/mesos/provisioner/backends/copy.cpp
Lines 200 (patched)
<https://reviews.apache.org/r/58408/#comment245282>

    I would add extra parathesis for the second half:
    ```
    if (os::exists(rootfsPath) &&
        (os::stat::isdir(rootfsPath) != ftsIsDir)) {
      ...
    }
    ```
    
    This improves readability because the reader might not understand the operator priority.
