Mauro,

Please don't reply to me directly: keep the list in Cc so that everyone
can participate to the discussion, and the discussion benefits to
everyone. Also, please don't top-post, this is considered bad practice.

The patches we want to see must be organized in a certain way (one
patch per new package, one patch for each logical change, etc.). Of
course, while you're doing your developing, you're probably going back
and forth between packages, and certainly not committing things
immediately in a way that is "clean" enough for submission.

So while all developers do for multi-patches series, they rewrite the
history of commits to produce a "clean" set of commits that is
appropriate for submission.

To do this, you need to use "interactive rebasing". You can learn about
it https://git-scm.com/book/en/v2/Git-Tools-Rewriting-History.

See above: use the interactive rebase functionality of Git.

One hint: for your big patch that adds all the packages, what you want
to do is:

 1/ Mark the patch as "edit" in your interactive rebase session
 2/ Git will stop at this patch

 3/ Use "git reset HEAD^" to de-apply the commit and put the changes
    back into your working tree

 4/ Create new commits.

Best regards,

Thomas
