I hope it is OK for e.g. Andrea. Disabling RETHUNK or IBT is not acceptable for a general-purpose kernel. If that constraint is introduced we either need to revert that patch in the Ubuntu kernel or disable Rust support. It would be nice to have a least something like CONFIG_RUST_IS_BROKEN_BUT_IM_HAPPY, off by default, and have `RUST_IS_BROKEN_BUT_IM_HAPPY || depends on !`. -Andrea > > Cheers, > Miguel
