Two small nitpicks: - for cocci patches I prefer if you include the (simplified, if it's a large one) semantic patch in the commit message. Cocci is really badly documented, it's good to see new examples of how. - threading seems funny in your series. Please generate mail threads using git format-patch --cover-letter $sha1_range and send them out using git send-email. That'll get all the details right. Also pls don't reply with new patches to an old series, that hides the patches and confuses the discussion. Just start a new thread (even when the patches are on the same or similar topic).
