Finally you can send your commit to the development mailing list and to the patchwork server.
If it is only a single commit (one patch) you can do a:
git send-email -1
which will send your last commit to the patchwork server and development mailing list.
Otherwise if your patch consists of 2 or more mails you have to use:
git send-email -1 -in-reply-to <mail Message-ID of first mail>
With this line you open up a thread.
