Kutulutsidwa kwa kernel ya Linux 5.9

Pambuyo pa miyezi iwiri ya chitukuko, Linus Torvalds anayambitsa kutulutsidwa kwa kernel Linux 5.9. Zina mwa zosintha zodziwika bwino: kuchepetsa kulowetsedwa kwa zizindikiro kuchokera ku ma module a eni kupita ku ma module a GPL, kufulumizitsa ntchito zosintha zinthu pogwiritsa ntchito malangizo a purosesa a FSGSBASE, kuthandizira kupsinjika kwa chithunzi cha kernel pogwiritsa ntchito Zstd, kukonzanso kuyika patsogolo kwa ulusi mu kernel, kuthandizira kwa PRP. (Parallel Redundancy Protocol) , bandwidth-aware scheduler in the deadline scheduler, preemptive packing of memory pages, capability flag CAP_CHECKPOINT_RESTOR, close_range() system call, dm-crypt performance performance, kuchotsa code kwa 32-bit Xen PV alendo, new slab memory kasamalidwe ka makina, njira "kupulumutsa" mu Btrfs, kuthandizira kwa inline encryption mu ext4 ndi F2FS.

Mtundu watsopanowu umaphatikizapo kukonza kwa 16074 kuchokera kwa opanga 2011,
kukula kwa chigamba - 62 MB (zosintha zinakhudza mafayilo a 14548, mizere ya 782155 ya code inawonjezeredwa, mizere ya 314792 inachotsedwa). Pafupifupi 45% ya onse operekedwa mu 5.9
zosintha zokhudzana ndi madalaivala a chipangizo, pafupifupi 15% ya zosintha ndizo
malingaliro okhudza kukonzanso kachidindo kamangidwe ka hardware, 13%
zokhudzana ndi stack network, 3% ku machitidwe amafayilo ndi 3% mkati
kernel subsystems.

waukulu zatsopano:

  • Memory ndi ntchito zadongosolo
    • Kumangika kutetezedwa ku kugwiritsidwa ntchito kwa zigawo za GPL polumikiza madalaivala omwe ali ndi kernel zomwe zimatumizidwa kunja kwa ma module okha pansi pa laisensi ya GPL. Mbendera ya TAINT_PROPRIETARY_MODULE tsopano yalandiridwa m'magawo onse omwe amalowetsa zizindikiro kuchokera kumagawo okhala ndi mbendera iyi. Ngati gawo la GPL likuyesera kulowetsa zizindikiro kuchokera ku gawo lomwe si la GPL, ndiye kuti gawo la GPL lidzalandira lebulo la TAINT_PROPRIETARY_MODULE ndipo silingathe kupeza zigawo za kernel zomwe zimangopezeka ku ma module okhala ndi chilolezo cha GPL, ngakhale gawolo lidatumizapo zizindikiro kuchokera gulu la "gplonly". Loko lakumbuyo (kutumiza EXPORT_SYMBOL_GPL kokha m'magawo omwe adatumiza kunja kwa EXPORT_SYMBOL_GPL), zomwe zingasokoneze ntchito ya madalaivala a eni ake, sizimayendetsedwa (ndi mbendera yokhayo yomwe imatengedwa, koma osati zomangira za GPL).
    • Zowonjezedwa kcompactd injini thandizo kwa kunyamula masamba okumbukira kumbuyo kuti muwonjezere kuchuluka kwamasamba akulu okumbukira omwe amapezeka ku kernel.
