Patch Review

Clean and minimal. The `KnownSize` trait is a well-scoped replacement for the unstable `core::mem::size_of_val_raw`.

One minor nit: the `//` comment in the import block at line 467 of the diff:

```rust
use core::mem::{
    align_of,
    size_of, //
};
```

The trailing `//` appears to be a formatting workaround (possibly to prevent `rustfmt` from collapsing the import to a single line). This pattern is used elsewhere in the kernel Rust code so it's consistent, but it's slightly unusual.

No functional issues. The `slice_ptr_len` feature gate is appropriate for `<*const [T]>::len()`.
