Josh Poimboeuf von Red Hat hat einen Patch f\u00fcr den Linux-Kernel ver\u00f6ffentlicht, der die Leistung des Tests «per_thread_ops» um 2,6 % steigert. Dieser Test bewertet die Anzahl der Operationen, die in einem einzelnen Thread ausgef\u00fchrt werden k\u00f6nnen. Der Patch nutzt Pointer-Masking, um die Anzahl langsamer Aufrufe von barrier_nospec() in der 64-Bit-Funktion copy_from_user() zu reduzieren, die zum Kopieren von Daten aus dem Benutzerspeicher in den Kernel verwendet wird. Linus Torvalds hat diese Optimierung bereits in den Kernel-Branch 6.12 \u00fcbernommen.
