Welcome and thanks for the patch!

The kernel requires a commit message.

In addition, please see (and maybe help review!) previous attempts:

  https://lore.kernel.org/rust-for-linux/20260729175305.723486-1-cianmcguire167@gmail.com/

Finally, the commit message should have the right tags, and Cc all the
maintainers and reviewers of the `RUST` subsystem from the
`MAINTAINERS` file.

Cheers,
Miguel
