Emva kweenyanga ezimbini zophuhliso, I-Linus Torvalds ityhila ukumiliselwa kwe inguqulo entsha ye-kernel ye Linux 5.16 kwaye apho phakathi kwezona nguqu ziphawulekayo yifutex_waitv inkqubo yokufowuna ukuphucula ukusebenza kwemidlalo yeWindows kwiWayini, ukulandelwa kweemposiso kwinkqubo yefayile nge fanotify, ukukwazi ukugcina inkumbulo yesokethi zenethiwekhi, ukuphathwa okuphuculweyo komthwalo ogqithisiweyo nge umthamo omkhulu wemisebenzi yokubhala, inkxaso yee-multi-drive hard drives, phakathi kwezinye izinto.
Inguqulelo entsha ifumene ukulungiswa kwe-15415 kubaphuhlisi be-2105, utshintsho oluchaphazela iifayile ze-12023, yongeza imigca ye-685198 yekhowudi, isuswe imigca ye-263867.
Ngokumalunga ne-44% yazo zonke iinguqu ezifakwe kwi-5.16 zihambelana nabaqhubi besixhobo, malunga ne-16% yeenguqu zihambelana nokuhlaziya ikhowudi ethile kwi-architectures ye-hardware, i-16% inxulumene ne-stack network, i-4% inxulumene neenkqubo zefayile kunye ne-4% ezinxulumene ne-kernel yangaphakathi kwiinkqubo ezisezantsi.
Eyona nto iphambili kwiLinux Kernel 5.16
Kule nguqulo intsha isixhobo sazisa izixhobo ezongezelelweyo ukujonga imeko yesixokelelwano sefayile kunye nokulandela iimpazamo. Inkxaso yokulandelela ibug iphunyeziwe okwangoku kuphela yeFS Ext4.
Tambien Ukuphatha ukuxinana kokubhala kuphuculwe Oku kwenzeka xa umthamo wemisebenzi yokubhala idlula umthamo we-drive kwaye inkqubo inyanzelekile ukuba ithintele izicelo zokubhala inkqubo de izicelo ezisele zidluliselwe zigqitywe.
Kwinguqulelo entsha, indlela ye-kernel esetyenziselwa ukufumana ulwazi malunga nokwenzeka komthwalo ogqithisiweyo kunye nemisebenzi yokubhloka iye yahlaziywa ngokupheleleyo.
I-Btrfs isebenzisa inkxaso yetekhnoloji ye-Zoned Namespace, esetyenziswa kwii-hard drives okanye i-NVMe SSDs ukwahlula indawo yokugcina kwiindawo ezenza amaqela eebhloko okanye amacandelo, apho kuphela ukongezwa ngokulandelelana kwedatha kuvunyelwe, ngelixa uhlaziywa lonke iqela leebhloko.
Indlela yokubhaliswa koluhlu lwenziwe ngokutsha, Apho inani lokukhangela kunye nokutshixa emthini liye lancitshiswa ukuze kuphuculwe ukusebenza kakuhle, ngaphezu kokongeza inkxaso elinganiselweyo yokusebenzisa ukunyanzeliswa xa ubhala amaphepha angaphelelanga, kunye nokukwazi ukuphazamisa ama-subpages.
Kwinkqubo yefayile Ext4, kuphela izilungiso zebug ezifakiweyo kunye nokubala ngokuchanekileyo kwetafile ye-inode iparameters yokuqalisa ivila.Kwinqanaba lesixhobo sebhloko, ukulungelelaniswa kuphunyeziwe oko kwandisa kakhulu ukusebenza kwekhonkco kwi-CPU cores.
Iinketho zokunyuka zongezwe kwiFS F2FS ukulawula uqhekeko lweefayile xa zigcinwe (umzekelo, ukulungisa iimpazamo zokusebenza ngogcino olwahlulwayo).
Umnxeba wenkqubo entsha yongeziwe, futex_waitv, ukujonga imeko yeefutexes ezininzi ngaxeshanye ngomnxeba wenkqubo enye. Olu phawu lufana nokusebenza kweWaitForMultipleObjects ekhoyo kwiWindows, ukulinganisa kwayo nge futex_waitv kunokuba luncedo ekuphuculeni ukusebenza kwemidlalo yeWindows eqhutywa kwiWayini okanye kwiProton.
Umphathi wongezwe kwi-Task Scheduler ethathela ingqalelo ukugcinwa kwe-cache kwi-CPU. Kwezinye iiprosesa, ezifana ne-Kunpeng 920 (ARM) kunye ne-Intel Jacobsville (x86), inani elithile le-CPU cores, ngokuqhelekileyo i-4, inokudibanisa i-L3 okanye i-L2 cache.
Iphunyeziwe imisebenzi emitsha emininzi esekwe kwindlela esezantsi ye-DAMON (I-Data Access Monitor) eyongeziweyo kwinguqulo yakamuva, evumela ukulandelela ukufikelela kwidatha kwi-RAM, ngokumalunga nenkqubo ekhethiweyo esebenza kwindawo yomsebenzisi.
Ukongeza koku, ukuphunyezwa kwe-algorithm yoxinzelelo zstd yahlaziywa kuguqulelo 1.4.10, eyenze ukuba kwenzeke ukunyusa kakhulu ukusebenza kwe-kernel subsystems ezininzi ezisebenzisa ucinezelo.
Kwakhona kuphawulwe ukuba ezinye zeendlela eziphambili zokukhusela i-seccomp () yokukhusela intambo ngokuchasene nokuhlaselwa kweSpecter zikhutshaziwe ngokungagqibekanga, ezazithathwa njengezingafunekiyo kwaye azizange zonyuse kakhulu ukhuseleko, kodwa zinefuthe elibi ekusebenzeni.
I-Hyper-V hypervisor ngoku ixhasa imowudi yokwahlula yomatshini, efihla imixholo yememori.
Ngoxa i-hypervisor I-KVM yongeza inkxaso kuyilo lwe-RISC-V kunye nokukwazi ukufuduka koomatshini benyani ngaphakathi kwendawo yokusingatha kwaphunyezwa kusetyenziswa i-AMD SEV kunye ne-SEV-ES izandiso, kunye ne-API eyongeziweyo yokufuduka okuphilayo kwe-AMD SEV (i-Secure Encrypted Virtualization) iindwendwe ezifihliweyo.
Kuyilo lwePowerPC, i STRICT_KERNEL_RWX imowudi yenziwe ngokungagqibekanga, ethi inqanda ukusetyenziswa kwamaphepha enkumbulo afumaneka ngaxeshanye ekubhaleni nasekuphunyezweni.
Ekugqibeleni kwicala labalawuli, i-amdgpu yazisa inkxaso yokuqala ye-DP 2.0 (I-DisplayPort 2.0) kunye ne-DisplayPort tunneling nge-USB4, ukongeza umboniso wenkxaso yomqhubi we-APU Cyan Skillfish kunye nenkxaso eyandisiweyo ye-APU Yellow Carp.
Umlawuli i915 uzinzisa ukuhambelana Intel Alderlake S chips kwaye iphumeza inkxaso ye-Intel PXP (iNdlela eKhuselweyo ye-Xe), ekwenza ukwazi ukusingatha iseshoni yemizobo ekhuselweyo kwiinkqubo ezineetshiphusi ze-Intel Xe.
Kumlawuli nouveau, umsebenzi wenziwe ukulungisa iimpazamo kunye nokuphucula isimbo sokubhala, inkxaso eyongeziweyo ye-X86 ehambelana neVortex CPU (Vortex86MX).
Gqibela ukuba unomdla wokwazi okungakumbi ngayo, ungazijonga iinkcukacha kwi ukulandela ikhonkco.
Ngokumalunga nohlaziyo lwale nguqulelo intsha, kufuneka bafike kwisithuba seeyure / iintsuku kumajelo asemthethweni osasazo lwakho okanye ungakhetha ukwenza ukudibanisa ngokwakho ngokufumana ikhowudi yomthombo. kwikhonkco elingezantsi.
