Izolo ILinus Torvalds umholi nomakhi wephrojekthi yeLinux Kernel ukhiphe uhlobo olusha lwalokhu, efinyelela kwiLinux 4.20.
Ngalokhu kukhululwa okusha i-Linux kernel entsha ikhule ngaphezu kwemigqa emisha engama-350,000, isakaze cishe izinguquko eziyi-14,000.
Ngaphezulu kwamafayela ayi-11.400 XNUMX aguquliwe. Lokhu kuletha ukukhishwa okusha ngokuhambisana nokukhishwa kwakamuva. Futhi, ukusatshalaliswa kwama-patches akuyona into engavamile, cishe izingxenye ezimbili kwezintathu kuthiwa zishayelwa abashayeli, okusele kunethiwekhi, izinhlelo zamafayela namathuluzi.
Lokhu akukhona ukukhishwa okukhulu nganoma yikuphi ukunweba komcabango. UTorvalds uthi: “iningi lawo ngamanethiwekhi (izilawuli, ukulungiswa kwenethiwekhi okuyisisekelo, i-bpf).
Kukhona nezinye izibuyekezo zokushayela okungezona ezenethiwekhi kanye nochungechunge oluhlehlisayo lwezinye izinguquko ze-x86 online asm ezidlulwe ukwesekwa okuzayo komhlanganisi.
Eposini lakhe uthi futhi:
Futhi njengengxenye yokuthi 'wonke umuntu usevele uthathe ikhefu', ngingabika ngenjabulo ukuthi sengivele nginezicelo ezimbalwa zokudonsa kusenesikhathi ebhokisini lami lokungenayo.
Ngigqugquzele abantu ukuthi bakwenze kanye futhi, ukuze abantu bakwazi ukukhululeka phakathi namaholide okuphela konyaka.
Eqinisweni, kungenzeka ngingaqali ukusebenza izinsuku ezimbalwa, kepha uma kungenjalo, masizame ukugcina amahora ajwayelekile.
Yini okusha in Linux Kernel 4.20
Ngale nguqulo entsha ye-Kernel, se bangeze ushintsho olusha futhi njengoba kushiwo, ukusekelwa okuningi kungeziwe kumadivayisi ikakhulukazi amakhadi evidiyo.
Abashayeli behluzo abasha
Isici esivelele ekushintsheni komshayeli kweLinux 4.20 yi-AMD.
Abathuthukisi bamakhadi weGraphics bangeze ikhodi eyengeziwe ngokulandelayo I-AMD Vega 20 GPU izolethwa kumakhadi amasha, acishe asekelwa ngokuphelele.
Ngokwengeziwe, ama-GPU aqanjwe ngegama anekhodi avela eRaven 2 nasePicasso manje asesekelwa nawo. Umshayeli wamahhala kaNvidia Nouveau uthole ukwesekwa kokuqala kwe-HDMI 2.0.
Izinhlelo zefayela
Izinhlelo zefayela kule kernel entsha zigxile ekwenzeni ngcono ukusebenza kwama-Btrfs. Kodwa futhi i-Ext4, i-XFS, i-F2FS, i-Device Mapper no-Ceph bathole ama-patches.
Ngesikhathi sokuthuthukiswa kweLinux 4.20, abathuthukisi babhekane nomsebenzi wokuxazulula inkinga engaholela ekulahlekelweni kwedatha ngaphansi kwezimo ezithile lapho usebenzisa i-Ext4.
Ekugcineni, kepha bekungekhona ukwehluleka kwesistimu yefayela okusabalalisiwe, i-bug yalandelwa ngemuva kosesho olude ku-Blk-MQ multi-queue block layer.
Kubaluleke nakakhulu ukuthi abashayeli be-block bakulungele ukushintshela enguqulweni entsha, njengoba inguqulo endala kungenzeka ukuthi yayivele isusiwe ngo-4.21. Njengengxenye yalokhu, izilawuli eziningi zamabhulokhi ziguqulelwe kwi-Multiqueue API.
Uhlelo olungaphansi kwenethiwekhi
Isitaki se-TCP sihumushelwa ukusebenzisa imodeli enquma isikhathi sokuqala ukuphuma kwephakethe ngalinye ekusabalalisweni kwethrafikhi ephumayo.
Imodeli esetshenzisiwe izama ukuxazulula izinkinga zokulinganisa esikhundleni semigqa ephumayo yamaphakethe, isakhiwo sokweqa ngokuya ngesibali sikhathi esinquma ukuthi isikhathi sokuqala singathunyelwa kanjani iphakethe ngalinye.
Lesi sakhiwo sikuvumela ukuthi wandise ukusebenza kahle kokusatshalaliswa kwamaphakethe athunyelwe kanye nokubala izikhathi zokwamukela nokwedlulisa ngokunemba okukhulu. (I-RTT, isikhathi sokuya nokubuya) ngesikhathi sokwakheka kokugeleza.
Ngakolunye uhlangothi, amandla okulayisha, ngohlobo lwezinhlelo ze-BPF, abaphathi abahlaziya izihloko zamaphakethe ekugelezeni kwenethiwekhi (ama-network flow dissectors) engeziwe, okwenza kube nokwenzeka ukufeza ukusebenza okuphezulu nokuphepha uma kuqhathaniswa ukuqaliswa okuphakanyisiwe phambilini kuC.
Ungayithola kanjani iKernel 4.20?
Le nguqulo entsha isiyatholakala ukuthi ingalandwa futhi labo abasha abafuna ukuyihlanganisa ohlelweni lwabo bangakwenza ngokushesha.
Ngokuqondene nalabo abathanda ukulinda amaphakheji akhishwe ukusatshalaliswa kwabo, kuyindaba yezinsuku lapho bekhishwa khona ukuze bavuselelwe ngokushesha.
