Ukukhishwa kwe-kernel Linux 5.15

Ngemva kwezinyanga ezimbili zokuthuthukiswa, uLinus Torvalds wakhipha i-kernel. Linux 5.15. Phakathi kwezinguquko eziphawuleka kakhulu: umshayeli omusha we-NTFS onokusekelwa kokubhala, imoduli ye-ksmbd enokusetshenziswa kweseva ye-SMB, uhlelo olungaphansi lwe-DAMON lokuqapha ukufinyelela kwememori, ukukhiya ama-primitive emodi yesikhathi sangempela, ukwesekwa kwe-fs-verity ku-Btrfs, ucingo lwesistimu ye-process_mrelease lwezinhlelo zokuphendula zememori ephansi, kanye nemoduli yokuqinisekisa ekude ye-dm-ima.

Inguqulo entsha ihlanganisa ukulungiswa okungu-13499 okuvela kubathuthukisi abangu-1888, usayizi wesichibi ungu-42 MB (ushintsho luthinte amafayela angu-10895, imigqa yekhodi engu-632522 yengezwe, imigqa engu-299966 isusiwe). Cishe u-45% wazo zonke izinguquko ezethulwe ku-5.15 zihlobene nezishayeli zedivayisi, cishe u-14% wezinguquko zihlobene nokubuyekeza ikhodi eqondene nezakhiwo zehadiwe, u-14% uhlobene nesitaki senethiwekhi, u-6% uhlobene nezinhlelo zamafayela, futhi u-3% zihlobene nesistimu ye-kernel yangaphakathi.

Okuqanjiwe okuyinhloko:

• I-Disk Subsystem, I/O kanye ne-File Systems
  • I-kernel yamukele ukuqaliswa okusha kohlelo lwefayela le-NTFS, elivulwe yiParagon Software. Umshayeli omusha angasebenza ngemodi yokubhala futhi asekele zonke izici zenguqulo yamanje ye-NTFS 3.1, okuhlanganisa izici zefayela ezinwetshiwe, uhlu lokufinyelela (ACLs), imodi yokucindezela idatha, umsebenzi ophumelelayo onezikhala ezingenalutho kumafayela (sparse) kanye nokudlala kabusha izinguquko ezivela ilogi yokubuyisela ubuqotho ngemva kokwehluleka .
  • Isistimu yefayela ye-Btrfs isekela indlela ye-fs-verity, esetshenziselwa ukulawula ngokusobala ubuqotho nobuqiniso bamafayela ngamanye kusetshenziswa ama-cryptographic hashes noma okhiye abahlobene namafayela, agcinwe endaweni yemethadatha. Ngaphambilini, i-fs-verity ibitholakala kuphela kumasistimu wefayela we-Ext4 kanye ne-F2fs.

    I-Btrfs iphinde yengeze ukusekelwa kokumepha ama-ID wabasebenzisi bezinhlelo zamafayela akhweziwe (ngaphambilini ayesekelwa amasistimu wefayela we-FAT, ext4 kanye ne-XFS). Lesi sici sikuvumela ukuthi uqhathanise amafayela omsebenzisi othile kuhlukanisi wangaphandle ogxunyekiwe nomunye umsebenzisi ohlelweni lwamanje.

    Ezinye izinguquko kuma-Btrfs zihlanganisa: ukungezwa ngokushesha kokhiye kunkomba yohlu lwemibhalo ukuze kuthuthukiswe ukusebenza kokudala ifayela; ikhono lokusebenza i-raid0 ngedivayisi eyodwa, kanye ne-raid10 ngezimbili (isibonelo, phakathi nenqubo yokuhlela kabusha uhlu); inketho "recue=ibadroots" ukuze uzibe isihlahla esingalungile; ukusheshisa umsebenzi "wokuthumela"; ukuncishiswa kwezingxabano zokukhiya ngesikhathi sokuqamba kabusha imisebenzi; amandla okusebenzisa imikhakha ye-4K kumasistimu anosayizi wekhasi lememori engu-64K.

Ngesikhathi esifanayo, i-Latin American Free Software Foundation idale inguqulo ye-kernel 5.15 yamahhala ngokuphelele - Linux-libre 5.15-gnu, ihlanzwe yi-firmware kanye nezinto zomshayeli eziqukethe izingxenye ezingezona ezikhululekile noma izingxenye zekhodi ezinobubanzi obunqunyelwe. Ukukhishwa okusha manje kubonisa umlayezo welogi mayelana nokuqedwa kokuhlanza. Izinkinga zokupakisha ze-mkspec zilungisiwe, futhi ukusekelwa kwamaphakheji e-snap kuthuthukisiwe. Ezinye izexwayiso ezikhiqizwe lapho kucutshungulwa ifayela lekhanda le-firmware.h zisusiwe. Ezinye izexwayiso (ifomethi-extra-args, amazwana, imisebenzi engasetshenziswanga, kanye neziguquguquko) manje sezivunyelwe ukuboniswa lapho kwakhiwe kumodi ye--Werror. Kwengezwe ukuhlanza komshayeli we-gehc-achc. Ikhodi ebuyekeziwe yama-blobs okuhlanza kubashayeli be-adreno, btusb, btintel, brcmfmac, aarch64, kanye ne-qcom kanye nezinhlelo ezingaphansi. Ukuhlanzwa kwabashayeli be-prism54 (kususiwe) kanye ne-rtl8188eu (kuthathelwe indawo yi-r8188eu) kunqanyuliwe.
