Rust fixes for 6.5-rc5

Hi Linus,

Please pull these fixes for Rust.

The oldest is a bit involved, and the other two are straightforward. The complex one has been in linux-next for 4 days and the others for 2 days, but I reworded yesterday the complex one to add a couple tags (no changes otherwise -- you can find the previous version of e.g. the oldest in linux-next at cf222ce8477c).

No conflicts expected. No changes to the C side.

Cheers,
Miguel
