Linus Torvalds tshaj tawm kev ruaj ntseg ntawm version 5.9.
Ntawm lwm qhov kev hloov pauv, nws tau qhia txog kev txhawb nqa rau FSGSBASE rau hauv 5.9 ntsiav, uas yuav tsum txhim kho cov ntsiab lus hloov pauv kev ua tau zoo ntawm AMD thiab Intel processors. FSGSBASE tso cai rau cov ntsiab lus ntawm FS / GS cov ntawv sau npe kom nyeem thiab hloov kho los ntawm cov neeg siv qhov chaw, uas yuav tsum txhim kho tag nrho cov kev ua tau zoo cuam tshuam los ntawm Spectre / Metldown vulnerabilities.

- ntxiv kev txhawb nqa rau NVMe tsav zoning commands (NVMe zoned namespaces (ZNS))
- kev txhawb nqa thawj zaug rau IBM Power10
- ntau yam kev txhim kho rau lub subsystem khaws cia, nce kev tiv thaiv kev siv GPL txheej rau kev sib txuas cov neeg tsav tsheb uas muaj tswv nrog cov khoom xyaw
- Cov qauv siv hluav taws xob (Energy Model moj khaum) tam sim no piav qhia tsis yog tsuas yog tus cwj pwm ntawm kev siv lub zog ntawm CPU, tab sis kuj ntawm cov khoom siv peripheral.
- Ntxiv REJECT ntawm PREROUTING theem rau Netfilter
- rau AMD Zen thiab cov qauv CPU tshiab, kev txhawb nqa rau P2PDMA thev naus laus zis tau ntxiv, uas tso cai rau koj siv DMA ncaj qha hloov cov ntaub ntawv ntawm lub cim xeeb ntawm ob lub cuab yeej txuas nrog lub npav PCI.
