Perhaps I'm missing something, but I wasn't able to reproduce this
problem (which I think is expected as the `kernel` crate already depends
on `pin_init`) with the following setup:

Tree: linux-next (next-20260122) [1]
      (includes latest changes from `rust-fixes` and `pin-init-next`)
Files: samples/rust/rust_*.rs, specifically rust_configfs.rs
rust-analyzer: 2024-04-29 (which corresponds to our MSRV), 2026-01-12

Could you share your environment details and a minimal reproducible
example?

Thanks!
