title: How to update a git superproject that depends on submodule commit under gerrit review?
body: <p>We have a git superproject that has one submodule. The submodule is under gerrit review.</p>
  
  <p>Our problem is that while changes are being reviewed in the submodule, (even if the submodule link to the commit under review has been committed on the superproject) they cannot be retrieved by other developers via 'git submodule update' unless they specifically fetch refs/changes/* in the submodule.</p>
  
  <p>I clearly state that we need other developers to be able to checkout code that is still under review in the submodule. So waiting for the code to be merged is not an viable choice. </p>
  
  <p>Is there a way to enable a developer getting the changes under review in the submodule via 'git submodule update' on the superproject that has the submodule link pointing to the commit under review ?</p>
