Seite 3: Nachzügler, Architektur-Perlen

Inhaltsverzeichnis

Nachzügler

Die Kernel-Entwickler Pflegen das Gros der Änderungen für eine neue Kernel-Version in der Merge Window genannten Phase am Anfang des Entwicklungszyklus in das Quellcodeverwaltungssystem ein. Dadurch stehen die wesentlichen Änderungen einer neuen Kernel-Version bereits Wochen vor deren Freigabe fest.

Gelegentlich nehmen die Kernel-Entwickler in der zweiten Phase des Entwicklungszyklus aber noch einige kleinere, zumeist nicht ganz so wichtige Änderungen der Kategorie "Die kleineren Perlen" in den Linux-Kernel auf – teilweise, nachdem das Kernel-Log über die entsprechenden Subsysteme des Kernels bereits berichtet hat. Einige solcher Nachzügler gab es diesmal bei den Dateisystemen:

• [    ] cifs: add attribute cache timeout (actimeo) tunable
• [ D  ] Documentation/filesystems/vfs.txt: fix ->repeasepage() description [ DN2] rbd: replace the rbd sysfs interface

Erwähnt werden sollen an dieser Stelle auch noch die Blog-Einträge "Removing the big kernel lock. A big deal?" und "Big kernel lock semantics at Andi Kleen's blog"
vom langjährigen Kernel-Hacker Andi Kleen. Er erklärt in diesen unter anderem, warum die im vierten Teil der Mini-Serie "Was 2.6.37 bringt" erläuterten Änderungen, durch die sich Kernel ohne BKL erstellen lassen, nicht so wichtig sind, wie sie von manchen dargestellt oder empfunden werden.

Einige Hintergründe zu den maßgeblich von Arnd Bergmann vorangetriebenen BKL-Änderungen hat eben dieser auch in einigen unter Realname verfassten Beiträgen im Forum zu einer Tickermeldung zum Thema erläutert.
