U-Linus Torvalds umemezele ukuzinziswa kwenguqulo 5.9.
Phakathi kwezinye izinguquko, wethule ukwesekwa kwe-FSGSBASE ku-5.9 kernel, okufanele ithuthukise ukusebenza kokushintsha umongo kuma-AMD kanye ne-Intel processors. I-FSGSBASE ivumela okuqukethwe kwamarejista e-FS/GS ukuthi kufundwe futhi kulungiswe kusuka esikhaleni somsebenzisi, okufanele kuthuthukise ukusebenza okuphelele okube khona ngemva kokuba ubungozi be-Specter/Metldown buchishiwe. Ukusekelwa ngokwako kwengezwe onjiniyela beMicrosoft eminyakeni embalwa edlule.
Futhi:
- ungeze ukwesekwa kwe-Radeon RX 6000 "RDNA 2"
- ungeze ukusekelwa kwemiyalo yezoni yedrayivu ye-NVMe (izikhala zamagama ezoniwe ze-NVMe (ZNS))
- ukwesekwa kokuqala kwe-IBM Power10
- ukuthuthukiswa okuhlukahlukene kusistimu engaphansi yesitoreji, ukuvikeleka okwandisiwe ekusetshenzisweni kwezingqimba ze-GPL zokuxhumanisa abashayeli bobunikazi nezingxenye ze-kernel
- imodeli yokusetshenziswa kwamandla (i-Energy Model framework) manje ayichazi nje kuphela ukuziphatha kokusetshenziswa kwamandla kwe-CPU, kodwa futhi namadivayisi asetshenziswayo
- Kwengezwe REJECT ku-PREROUTING isigaba ku-Netfilter
- kumamodeli e-AMD Zen kanye namamodeli e-CPU amasha, ukwesekwa kobuchwepheshe be-P2PDMA kungeziwe, okukuvumela ukuthi usebenzise i-DMA ukudlulisa ngokuqondile idatha phakathi kwememori yamadivayisi amabili axhunywe ebhasini le-PCI.
