Primarily fly-by style comments.


src/slave/containerizer/mesos/isolators/cgroups/net_cls.cpp (line 58)
<https://reviews.apache.org/r/42587/#comment178825>

    We generally leave a line before the comment and the TODO to correctly 
demarcate where the comment ends and where the TODO begins.
    
    ```
    // comments
    //
    // TODO(asridharan): 
    //
    ```

    What does `handles.size()` returns. I am assuming its an `unsigned in`t and 
hence should fail compilation with `-Wsign-compare` on GCC.
    
    Why don't we just do `size_t count = 1`?



src/slave/containerizer/mesos/isolators/cgroups/net_cls.cpp (line 95)
<https://reviews.apache.org/r/42587/#comment178832>

    Should fit on one line?



src/slave/containerizer/mesos/isolators/cgroups/net_cls.cpp (line 96)
<https://reviews.apache.org/r/42587/#comment178833>

    I see that we name `NetClsHandles` as `handles`.
    
    Why not name `NetClsHandle` as just `handle`?

    Remove period at the end.

    How about simplifying this to:
    
    ```
    if (condition) {
      return Nothing();
    }
    
    return Error(...);
    ```

    How about simplifying this to:
    
    ```
    if (condition) {
      return Nothing();

    return Error(...);
