Add missing filesystem operations about tokio-uring

[kaimast]

We should maybe keep this open until the others are implemented too?

[kaimast]

Is there going to be another io-uring release soonish? I just added a create_dir call on this branch, but it requires the git version of that crate.

[Noah-Kennedy]

Yes, there should be a release soon.

[Noah-Kennedy]

@kaimast version 0.2.0 has been released.

[kaimast]

Thanks! I was talking about the io-uring crate though.

That close seemed to have been done automatically. Anyway, no harm. Definitely some file system operations left.

Is tokio::fs::canonicalize also an operation we can support?

The io_uring API doesn't support anything like a canonicalize (or in Unix terms, a realpath) so to avoid using the std or the tokio canonicalize, this crate, or just as easily I think, a 3rd party package, could build the logic from this crate's StatxBuilder.

That's not to say we wouldn't accept a PR that essentially duplicated a realpath based on our statx. But any suggested additions would have to be compatible with our license and I don' know if even starting with a BSD version of realpath is an acceptable approach.

[Icelk]

I understand. Thanks.
