Christoph Hellwig lahkus dma-mapping ja configfs alams\u00fcsteemide hooldaja positsioonilt. Lahkumine piirdus hooldajate nimekirjast eemaldamise taotluse saatmise ja teatega \u00fcleandmisest \u00fclej\u00e4\u00e4nud hooldajatele. dma-mapping alams\u00fcsteemi hooldust j\u00e4tkab Marek Szyprowski Samsungist, samas kui configfs-i hooldust juhib Joel Becker Oracle'ist. <\/p>\n

Christoph Hellwig j\u00e4\u00e4b endiselt NVM Express, vmalloc ja FreeVXFS alamhalduri hulka. Varasemalt kuulus Christoph Linux Foundation'i juhtivasse tehnilisse komiteesse ja osales selliste alamhalduri nagu XFS, KVM<\/a>, Trace events, SCSI ja Slab Allocator arendamisel, samuti t\u00f6\u00f6tas PowerPC arhitektuuri hooldamisega Linuxi tuumas. Lisaks oli Christoph hagi esitaja kohtuvaidluses VMware'iga, mis k\u00e4is GPL litsentsi rikkumise \u00fcle. <\/p>\n

dma-mapping ja configfs alams\u00fcsteemide toetamise l\u00f5petamine on tingitud Linus Torvalds'i avaldusest, et ta kavatseb lisada Rusti keeles sidumist tuuma s\u00f5ltumatult alam-s\u00fcsteemide hooldajate n\u00f5usolekust, mille jaoks need sidemed on loodud. Jaanuaris keeldus Christoph p\u00f5him\u00f5tteliselt v\u00f5tmast tuuma Rust-sidumist DMA funktsioonide t\u00f6\u00f6tluseks, mis t\u00f5i kaasa konflikti, mille tulemusena lahkusid tuumast Nouveau ja ARM\/Apple alam-s\u00fcsteemide hooldajad. 24. veebruaril pakkusid Rust for Linux projekti arendajad v\u00e4lja plaastri configfs failis\u00fcsteemi abstraktsioonikihi jaoks, mille juhtimisega tegi koost\u00f6\u00f6d Christoph Hellwig. Christoph ei osalenud oma alam-s\u00fcsteemi uue Rust-sidumise arutelus ning m\u00f5ne p\u00e4eva p\u00e4rast eemaldus ta dma-mapping ja configfs hooldajate nimekirjast. <\/p>\n

Christoph Helwig peab eba\u00f5igeks kasutada mitmeid programmeerimiskeeli keerulistes projektides nagu Linuxi ydur. Christoph usub, et segatud koodibaasid muudavad hooldajate t\u00f6\u00f6 keerulisemaks, kuna need seavad hooldajad s\u00f5ltuvusse teise keele koodist. Eelk\u00f5ige juhul, kui olemas on Rusti m\u00e4hised, peavad C keeles kirjutatud alamprogrammide arendajad arvestama, kuidas nende muudatused m\u00f5jutavad m\u00e4histe j\u00e4tkuvat toimimist. Iga C keeles tehtav muudatus andmestruktuurides v\u00f5i sisefunktsioonides v\u00f5ib vajada m\u00e4histe koodi muutmist, seet\u00f5ttu on vajalik j\u00e4lgida ja s\u00fcnkroonida C koodis m\u00e4histele m\u00f5jutavaid muudatusi Rusti koodiga. <\/p>\n

Kernide v\u00e4ljat\u00f6\u00f6tamise k\u00e4igus esines juba juhtumeid, kus pull-taotlusi, mis kandsid muudatusi m\u00e4luhalduse alams\u00fcsteemis, l\u00fckati tagasi, kuna see muudatus p\u00f5hjustas t\u00f5rke katsete k\u00e4igus kompileerida tuuma koos Rusti toe aktiveerimisega. T\u00f5rge toimus Rusti sidumiste (bindgen) genereerimise koodiga mitte\u00fchtlase tasakaalu t\u00f5ttu ning viis selleni, et m\u00e4luhalduse alams\u00fcsteemi hooldajad, kes edendasid muudatust, mis oli t\u00e4ielikult korrektselt kodeeritud C keeles ja tuumas tervikuna, s\u00f5ltusid tuumas olevast valikulisest kolmandate osapoolte koodist, mille eest vastutavad teised inimesed. <\/p>\n

Linus Torvalds arvab, et Christoph Hellwigil ei ole \u00f5igus blokeerida Rust-i m\u00e4histe vastuv\u00f5ttu DMA alamv\u00f5rgu jaoks, kuna nende m\u00e4histe kood ei puuduta DMA Mapping alamv\u00f5rgu koodi ja on ellu viidud eraldi kaustas, mida haldab eraldi hooldaja. Linus v\u00f5rreldes Christoph'i tegevust katsega kontrollida DMA alamv\u00f5rgu kasutusala, kuna hooldajad vastutavad ainult oma alamv\u00f5rgu koodi eest, mitte selle eest, kuidas ja kelle poolt selle koodi tulemusi kasutatakse. N\u00e4iteks v\u00f5ivad baasalamv\u00f5rkude koodimuudatused tekitada probleemide kuhjumise mingite draiverite t\u00f6\u00f6tamisel, kuid see ei ole p\u00f5hjus sekkuda uute draiverite vastuv\u00f5ttu.
