Could you please disable `CONFIG_RETPOLINE` and
`CONFIG_X86_KERNEL_IBT` for the Rust config? (e.g. like in KernelCI
https://github.com/kernelci/kernelci-core/blob/main/config/core/build-configs.yaml#L410)
We are discussing whether to add a `depends on !` or other approaches
on the kernel side, which may make that redundant, but meanwhile it
would be great if you could update the config.
Thanks!
Cheers,
Miguel

You are welcome, and thanks for the input that we are not aware of.
BTW: It's ok not to Cc me explicitly, as lkp@intel.com account is the mail for

This allows us to run some code when the guard is dropped (e.g.,
implicitly when it goes out of scope). We can also prevent the
guard from running by calling its `dismiss()` method.

This allows us to use the unit type `()` when we have no object whose
ownership must be managed but one implementing the `ForeignOwnable`
trait is needed.

this should really be `core::ptr::invalid(1)`. That's currently
unstable, but can be equivalently written as
`NonNull::<()>::dangling().as_ptr()`.
This has a different semantic meaning from `as` since it explicitly
suggests an invalid provenance and thus will not alias with other
pointers. (Although I don't think compiler currently can take advantage
of this fact yet)

We talked about starting to use `strict_provenance` when it came out
-- what is the latest status? i.e. do you know if it is expected that
it will pass FCP etc.? (my understanding originally was that it was an
experiment).
If it is likely to become stable, then I agree it could be nice to
start using it before a lot of kernel code gets written without it.
Thanks Gary!
Cheers,
Miguel

From what I remember the feeling was positing into hace `strict_provenance`
Here is the last meeting that was back in August
https://rust-lang.zulipchat.com/#narrow/stream/213817-t-lang/topic/Stabilizing.20strict.20provenance.20APIs.3F
I guess, we could just put a fix me around the actual code, I feel that the Gary change deserve a
own patch with the own description.
Cheers!
Vincent.

Thanks Vincent! Yeah, as far as I understand Gary was in that meeting
(in October).
If there has not been anything after that, then I guess it is still
the case that provenance will probably happen (for better or worse,
depending on the perspective :) and that a subset of the APIs may get
stabilized first.
Cheers,
Miguel

This has the wrong type, but I agree with the spirit of the
suggestion. I'll add it to V2.
