Die kleineren Perlen
Die englischen Überschriften von zahlreichen weiteren nicht ganz so wichtigen, aber keineswegs unbedeutenden Änderungen finden sich in der folgenden Liste. Die Einträge verlinken genau wie viele der Verweise im vorangegangenen Text auf den jeweiligen Commit im Webfrontend des Hauptentwicklungszweigs von Linux. Dort liefern normalerweise der Commit-Kommentar und der Patch selbst zahlreiche weitere Informationen zur jeweiligen Änderungen.
