FWIW, I think Russell has been away dealing with personal stuff recently: https://lore.kernel.org/aeDSTIS9-TDSihbX@shell.armlinux.org.uk/ So I doubt he would fight you taking it, given that it is Rust related. I am rather selfishly motivated to have it picked up and merged because I have to remember to pass KCONFIG_ALLCONFIG=<(echo CONFIG_RUST=n) every time that I have to test arm allmodconfig. But don't feel rushed to pick it up if you want to wait for a formal agreement on the path forward. -- Cheers, Nathan
