Thanks for the report -- this should be already fixed in `rust-next`
for tomorrow (requirement changed from `!FINEIBT` to `!CALL_PADDING`),
please see https://lore.kernel.org/rust-for-linux/CANiq72=B9NmC=1eSaOrg7XutjueQsSXGcBQb7dQFPuL0SFjPsA@xxxxxxxxxxxxxx/

If you can confirm it is, that would be great, thanks! i.e. you will
need either to disable `CALL_PADDING` or use a newer Rust compiler
version.

By the way, I think you meant next-202409176, not next-20240917?

Cheers,
Miguel
