Sele sinalo apha uguqulelo olutsha lwekernel yenkqubo (ii) esetyenziswa ngabahleli nabafundi beeblogi ezifana nale kakhulu. Ngesi sihlandlo, emva koko 5.18 yayilithuba lika I-Linux 5.19, leyo uLinus Torvalds esandula ukubhengeza ukukhululwa kwayo. Xa ndisithi "yayilithuba lakhe", ndithetha ukuba yayiyinto enengqondo ukuyenza, kwaye kube njalo ukusukela oko kwaqala uphuhliso, kodwa bekukho ukuthandabuza malunga nokuba elandelayo iya kuba yiLinux 5.20 okanye Linux 6.0. Kodwa eli nqaku limalunga nenguqulo yakutshanje ezinzileyo, ukukhululwa kwayo ngoku ngokusemthethweni.
I-Linux 5.19 lukhupho olukhulu. Kakade kwifestile yokudibanisa kwaqinisekiswa ukuba kuya kubakho utshintsho oluninzi, nangona inani labo alizange lenze i-kernel ikhule ngobukhulu. Apha ngezantsi kukho uluhlu kunye ne ezona ndaba zibalaseleyo, thatha ukusuka Phoronix, isithuba esikhethekileyo esilandela ngokusondeleyo uphuhliso lweLinux, phakathi kwezinye izinto ezifana nohlalutyo lwayo oludumileyo kunye nothelekiso lwazo zonke iintlobo zehardware.
