Submit patches. Who(m) decides what's applied or not?

It was the refs/for/master which I thought to be the ‘origin’ dunno why. Thats why I didnt include it. I think my patch will denied because of whitespaces that I didnt see before. Can I withdrawal it?

See the Updating your commit(s) on that same page. You have to git commit --amend your changes and, very important, add the “Change-ID” from your patch in the last line.
