Inhaltsverzeichnis

Die kleinen Perlen: Infrastruktur

Viele kleinere, aber keineswegs unbedeutende Neuerungen finden sich in der folgenden Liste mit den englischen Commit-Überschriften der jeweiligen Änderung. Die Einträge verlinken genau wie viele der Verweise im vorangegangenen Text auf das Webfrontend des von Linus Torvalds gepflegten Git-Zweigs mit den "offiziellen" Kernel-Quellen, der aufgrund des Einbruchs in kernel.org derzeit Github gehostet ist. Der über diese Links angezeigten Commit-Kommentar und der darunter ausgegebene Patch liefern zahlreiche weitere Informationen zur jeweiligen Änderungen.

Vor jedem Link finden sich in eckigen Klammern einige Buchstaben und Zahlen. Ein "C" kennzeichnet Patches mit Änderungen an Kconfig-Dateien, welche die Konfigurationsoptionen samt der zugehörigen Hilfetexte enthalten, die bei der Kernel-Konfiguration über "make menuconfig" oder "make xconfig" angezeigt werden. Ein "D" steht bei Patches, die die Dokumentation verändern, die im Kernel-Zweig unterhalb von Documentation/ liegt. Ein "N" weist Änderungen aus, die eine neue Datei anlegen. Die Zahl vermittelt einen groben Eindruck zur Größe des Patches: eine "1" kennzeichnet Änderungen, die inklusive Kommentar zwischen 10 und 20 KByte groß sind, eine "2" für solche, die zwischen 20 und 30 KByte Umfang haben; Änderungen ohne Zahl sind kleiner als 10 KByte, Patches mit einer "9" hingegen 90 KByte oder größer.
