Rust configfs changes for v7.4-rc1

Hi Breno,

Here is the first pull request from me to you for the Rust configfs abstractions. Please note that I neglected to push these three patches to the remote that is picked up by linux-next (just did it now). However, I tried the merge and verified everything works under my usual configurations, so we should be fine.

Best regards,
Andreas Hindborg

Hello Andras,

Do you want me to pull your tree under mine and send to linus, or, is this just a FYI?

I am happy in either way,
--breno

Yes, please pull my tree into yours before sending your changes to Linus.

Best regards,
Andreas Hindborg

Pulled into configfs-next, thanks.
