> ClientProtocol.createSymlink parameter dirPerm invalid

> {code}
> * @param link The path of the link being created.
> * @param dirPerm permissions to use when creating parent directories
> * @param createParent - if true then missing parent dirs are created
> * if false then parent must exist
> {code}
> According to javadoc, auto created parent dir's permissions will be dirPerm,
> but in fact directory permissions are always inherit from parent directory
> plus u+wx.
> IMHO, createSymlink behavior should be the same as create, which also inherit
> parent dir permission, so the current behavior makes sense, but the related
> dirPerm parameters should be removed cause it is invalid and confusing.
