Linus Torvalds blev tilsluttet<\/a><\/noindex> til diskussion muligheder<\/a><\/noindex> tilf\u00f8jelse af v\u00e6rkt\u00f8jer til udvikling p\u00e5 Rust-sprog til Linux-kernen. Josh Triplett fra Intel, der arbejder p\u00e5 projekt<\/a><\/noindex> at bringe Rust-sprog op p\u00e5 niveau med C-sprog inden for systemprogrammering, et h\u00e5ndskrevet patch til rettelsen.<\/a><\/noindex> I det tidlige stadium at tilf\u00f8je en Kconfig-indstilling for at st\u00f8tte Rust, som ikke ville f\u00f8re til, at den blev inkluderet i afh\u00e6ngighederne af Rust-kompilatoren ved udf\u00f8relse af build med indstillingerne \u00abmake allnoconfig\u00bb og \u00abmake allyesconfig\u00bb og som ville tillade mere frit at eksperimentere med Rust-koden. En lignende metode blev implementeret ved tilf\u00f8jelsen<\/a><\/noindex> i kernen til eksperimentel support for bygninger i Clang under optimeringsmetoder ved linktid (LTO, Link Time Optimization), hvorefter det er planlagt at tilf\u00f8je support<\/a><\/noindex> bygning med beskyttelse af kommandoernes udf\u00f8relsesflow (CFI<\/a><\/noindex>, Control-Flow Integrity).<\/p>\n

Linus var ikke enig og udtrykte bekymring for, at den f\u00f8rste st\u00f8tte til Rust ville v\u00e6re ustestet under bygningen og ville risikere at sidde fast i sit eget sump, hvor en lille gruppe interessenter tester koden kun under deres specifikke forhold og tilf\u00f8jer forkerte ting, da de forbliver skjult og ikke kommer frem under testning af kernen i andre milj\u00f8er. <\/p>\n

If\u00f8lge Linus b\u00f8r den f\u00f8rste Rust-driver pr\u00e6senteres i et simpelt format, hvor fejl er \u00e5benlyse og lette at opdage. For at forenkle testningen anbefalede han at g\u00f8re som ved test af versioner af C-kompilatoren og underst\u00f8ttede flag \u2014 at kontrollere, om Rust-kompilatoren er til stede p\u00e5 systemet, og aktivere dens st\u00f8tte, hvis den er installeret. <\/p>\n
