Die kleinen Perlen

Die folgende Aufstellung listet die englischen Commit-Überschriften einiger weiterer Neuerungen. Ähnlich wie viele Verweise im vorangegangenen Text verlinken die Einträge auf das Webfrontend des von Linus Torvalds gepflegten Git-Zweigs auf Kernel.org. Dort finden Sie den Commit-Kommentar und den eigentlichen Quellcode-Patch, die zahlreiche weitere Informationen zur jeweiligen Änderung liefern.

Ein "C" im Bereich "[  ]" kennzeichnet Commits mit Änderungen an Kconfig-Dateien, welche die Konfigurationsoptionen samt der zugehörigen Hilfetexte enthalten. Mit "I" ausgezeichneten 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.

Weitere Hintergründe und Informationen rund um Entwicklungen im Linux-Kernel und dessen Umfeld finden sich in den vorangegangenen Kernel-Logs auf heise open. Neue Ausgaben des Kernel-Logs werden auf den Identi.ca- und Twitter-Konten "@kernellog" erwähnt; die englischen, bei den Kollegen von "The H" erscheinenden Übersetzungen auf den Identi.ca- und Twitter-Konten "@kernellog2". Gelegentlich zwitschert der Autor des Kernel-Logs unabhängig davon über einige Kernel-Log-Themen bei Identi.ca und Twitter als "@kernellogauthor". (thl) (thl)
