Christoph Hellwig, spr\u00e1vce subsyst\u00e9mu DMA, KVM, Slab Allocator a architektury PowerPC v j\u00e1d\u0159e Linux, z\u00e1sadn\u011b odm\u00edtaj\u00edc\u00ed zahrnout Rustov\u00e9 obalit do j\u00e1dra subsyst\u00e9mu DMA, se p\u0159ipojil k diskusi o pravidlech \u00fadr\u017eby Rustu v j\u00e1d\u0159e, kter\u00e9 byly zve\u0159ejn\u011bny projektem Rust for Linux. Podle Christopha jsou tato pravidla zbyte\u010dn\u00e1, dokud nebudou dohodnuta se komunitou a zahrnuta do dokumentace k j\u00e1dru. <\/p>\n

Christoph tak\u00e9 upozornil na to, \u017ee v pravidlech je uvedena nespr\u00e1vn\u00e1 informace t\u00fdkaj\u00edc\u00ed se toho, \u017ee spr\u00e1vci mohou samostatn\u011b rozhodovat o zahrnut\u00ed k\u00f3du souvisej\u00edc\u00edho s Rustem do sv\u00fdch subsyst\u00e9m\u016f. Podle Christopha v osobn\u00edm rozhovoru Linus Torvalds prohl\u00e1sil, \u017ee je pevn\u011b odhodl\u00e1n zahrnout Rustov\u00fd k\u00f3d do j\u00e1dra, bez ohledu na n\u00e1mitky spr\u00e1vc\u016f.

Christoph tak\u00e9 znovu p\u0159irovnal roz\u0161\u00ed\u0159en\u00ed Rustov\u00fdch obal\u016f k rakovinov\u00e9mu tumoru, kter\u00fd se roz\u0161\u00ed\u0159\u00ed do v\u0161ech subsyst\u00e9m\u016f j\u00e1dra a povede k fragmentaci.

Kristof se pt\u00e1 na c\u00edl zaveden\u00ed Rustu do j\u00e1dra. Pokud je c\u00edlem \u0159e\u0161en\u00ed probl\u00e9m\u016f s bezpe\u010dnost\u00ed, kter\u00e9 vznikaj\u00ed p\u0159i n\u00edzko\u00farov\u0148ov\u00e9 pr\u00e1ci s pam\u011bt\u00ed, je nejprve pot\u0159eba modernizovat existuj\u00edc\u00ed k\u00f3d. Vzhledem k tomu, \u017ee \u00fadr\u017eb\u00e1\u0159i bolestn\u011b reaguj\u00ed i na trivi\u00e1ln\u00ed v\u011bci, jako jsou kontroly na p\u0159ete\u010den\u00ed cel\u00fdch \u010d\u00edsel, nen\u00ed jasn\u00e9, jak lze p\u0159ekonat mezeru mezi jednou \u010d\u00e1st\u00ed j\u00e1dra, kter\u00e1 neakceptuje ani jednoduch\u00e1 pravidla pro zaji\u0161t\u011bn\u00ed bezpe\u010dnosti, a druhou \u010d\u00e1st\u00ed, je\u017e dodr\u017euje p\u0159\u00edsn\u00e1 pravidla.
