lgtm but there's still more clippy failures, could you fix those?

There are 2 lints "a const item should not be interior mutable":

const EMPTY_CELL: Cell<T> = Cell::new(0);
const INIT: UnsafeCell<MaybeUninit<T>> = UnsafeCell::new(MaybeUninit::uninit());

I'm not sure what to do here without breaking something.

Clippy docs just suggest to replace const with static.

But that doesn't compile, so it's not even an option.

you can remove the const, and do buffer: [const { UnsafeCell::new(MaybeUninit::uninit()) }; N]. this is inline const block, stabilized in 1.79.

Thanks. Done.
