Sabuwar sigar ta kawar da maganganun da aka yi yayin tattaunawar sigar farko ta faci. Linus Torvalds ya riga ya shiga cikin tattaunawar kuma ya ba da shawarar canza dabaru don sarrafa wasu ayyuka.
Ka tuna cewa canje-canjen da aka gabatar sun ba da damar yin amfani da Rust azaman harshe na biyu don haɓaka direbobi da samfuran kwaya. Ana gabatar da tallafin tsatsa azaman zaɓi wanda ba a kunna shi ta tsohuwa ba kuma baya haifar da shigar da tsatsa azaman dogaron ginawa da ake buƙata don kernel.

Canje-canjen da aka fi sani a cikin sabon sigar faci:
- An kuɓutar lambar keɓewar ƙwaƙwalwar ajiya daga yuwuwar haifar da yanayin "firgita" lokacin da kurakurai kamar fitar da ƙwaƙwalwar ajiya suka faru. An haɗa bambance-bambancen ɗakin karatu na Rust alloc, wanda ke sake yin rikodin don magance gazawa, amma babban makasudin shine don canja wurin duk abubuwan da ake buƙata don kernel zuwa babban bugu na allo (an riga an shirya canje-canje kuma an canza su zuwa daidaitattun.

Bugu da ƙari, an ambaci wasu ayyukan kamfanoni masu alaƙa da amfani da Rust a cikin kwaya:
- Microsoft ya nuna sha'awar shiga cikin aikin don haɗa tallafin Rust a cikin kwaya na Linux kuma yana shirye don samar da aiwatar da direbobi don Hyper-V akan Rust a cikin watanni masu zuwa.
- ARM yana aiki don haɓaka tallafin Rust don tsarin tushen ARM. Aikin Rust ya riga ya ba da shawarar canje-canje waɗanda za su sanya tsarin 64-bit ARM ya zama dandalin Tier 1.
- Google kai tsaye yana ba da tallafi ga aikin Rust don Linux, yana haɓaka sabon aiwatar da tsarin sadarwa na Binder a cikin Rust, kuma yana la'akari da yuwuwar sake yin aikin direbobi daban-daban a cikin Rust. Ta hanyar ISRG (Rukunin Binciken Tsaro na Intanet), Google ya ba da kuɗi don aiki don haɗa tallafin Rust a cikin kernel na Linux.
- IBM ta aiwatar da tallafin kwaya don Rust don tsarin PowerPC.
- Laboratory Research na LSE (Systems Research Laboratory) ya haɓaka direban SPI a cikin Rust.
