Ein "C" im Bereich "[  ]" kennzeichnet Commits mit Änderungen an Kconfig-Dateien, welche die Konfigurationsoptionen samt der zugehörigen Hilfetexte enthalten. Mit "I" ausgezeichnete Patches rüsten neue PCI- oder USB-IDs nach; jene mit "D" verändern die dem Kernel beiliegende Dokumentation; Commits mit "N" legen neue Dateien an. Die Zahl vermittelt einen groben Eindruck zur Größe des Patches: Eine "1" kennzeichnet Patches, die inklusive Kommentar zwischen 10 und 20 KByte groß sind; Patches mit einer "9" sind 90 KByte oder größer.
