Na Linux mailing listi predstavljena je \u0161esta verzija zakrpa s implementacijom mehanizma Kexec HandOver (KHO), koji razvijaju in\u017eenjeri iz kompanija Amazon, Microsoft i Google. Zakrpe su ve\u0107 prihva\u0107ene u mm-everything granu, u kojoj se akumuliraju promjene za budu\u0107u granu jezgre 6.16, vezane uz upravljanje memorijom. Na temelju Kexec HandOver, kompanija Google razvija podskupinu Live Update Orchestrator (LUO), koja omogu\u0107ava ponovno pokretanje jezgre bez zaustavljanja rada ure\u0111aja. <\/p>\n

Kexec HandOver pru\u017ea mogu\u0107nosti za pokretanje nove jezgre iz stare bez gubitka stanja sustava. Trenutno poziv kexec() radi samo kao bootloader, koji jednostavno pokre\u0107e novu jezgru, koja nakon toga potpuno reinitializuje sustav, \u0161to je ekvivalentno ponovnom pokretanju, samo bez sudjelovanja firmware-a. Predlo\u017eena serija zakrpa implementira drugi pristup. Prije prijenosa upravljanja novoj verziji jezgre, stanje klju\u010dnih podskupina jezgre se serijalizira u memorijskoj regiji koja ne\u0107e biti pogo\u0111ena daljnjim operacijama. Nova jezgra, primaju\u0107i upravljanje, obnavlja serijalizirano stanje. Sa stanovi\u0161ta ostalih programa, operacija zamjene jezgre je neprimjetna. <\/p>\n

Kexec HandOver mo\u017ee biti koristan u situacijama kada zaustavljanje nije dozvoljeno i potrebno je osigurati neprekidan rad pojedinih ure\u0111aja. Na primjer, na serverima virtualizacije, Kexec HandOver se mo\u017ee koristiti za a\u017euriranje jezgre (i hipervizora) KVM<\/a>), ne utje\u010du\u0107i na memoriju koju koriste virtualne ma\u0161ine i o\u010duvaju\u0107i stanje njihovog izvo\u0111enja.
