title: Gerrit and repo
body: <p>I uploaded a patch X on gerrit, but by mistake I included a file Y that I shouldn't have included in the patch. Now, I want to submit a new patchset for X, without the file Y. Is it possible to do that</p>
  
  <p>Steps to remove Y from new Patchset for X<br>
  Manually removed all the changes I made in Y  (Not the best way to do that, but it removed Y from new Patchset for X)<br>
  <code>git add .<br>
   git commit -s --amned<br>
   repo upload .</code></p>
