Linus Torvalds je pripremio skup zakrpa za podsustav upravljanja memorijom u Linux kernelu, koji implementira optimizaciju za \u010ditanje malih blokova podataka iz stranica ke\u0161a bez atomskog mijenjanja broj\u010danika referenci (refcount) u strukturi folio. U tekstu zakrpe navedeno je da su promjene, povezani testovi i skica bilje\u0161ke kreirani uz pomo\u0107 AI asistenta Claude Code pod nadzorom Torvaldsa. Promjena je dodana u posebnu granu kernel-a noref-filemap-read-with-llm i jo\u0161 nije jasno ho\u0107e li biti premje\u0161tena u glavnu granu ili je to samo unutarnji eksperiment.<\/p>\n

Tijekom testiranja, zahvaljuju\u0107i zakrpama, uspje\u0161no je pove\u0107ana propusnost \u010ditanja malih datoteka u konfiguraciji s 8 niti sa 9.9-10.4 na 30-33 milijuna operacija u sekundi (pove\u0107anje od 3 puta), s 4 niti \u2014 s 8.9-11.6 na 25-26 milijuna\/sek. (pove\u0107anje od 2 puta), a pri jednonitnom optere\u0107enju sa 7.9-8.1 na 8.8-8.9 milijuna \/sek. Pove\u0107anje performansi obja\u0161njava se time da pri istovremenom pristupu stranici predmemorije dolazi do sna\u017ene konkurencije izme\u0111u niti u pristupu predmemoriji. Na primjer, kada 8 niti poku\u0161ava istovremeno \u010ditati po 16 bajtova podataka, 99.92% vremena se tro\u0161i ne na samo \u010ditanje, ve\u0107 na \u010dekanje pristupa broja\u010du referenci.<\/p>\n

U zakrpi, kako bi se osigurala to\u010dnost podataka, umjesto postavljanja zasebnih zaklju\u010davanja, promjenama broj\u010danika referenci ili me\u0111uspremanja, koristi se zaobilazno rje\u0161enje koje koristi odgo\u0111eno osloba\u0111anje memorije sa sinkronizacijom putem mehanizma RCU (Read-Copy-Update). Predlo\u017eena metoda u zakrpi jam\u010di da stranica memorije ne\u0107e biti fizi\u010dki oslobo\u0111ena dok \u010ditaju\u0107i niti ne zavr\u0161i s kopiranjem podataka.
