rust: block: fix wrong usage of lockdep API

2024-08-21T11:28:13Z

When allocating `struct gendisk`, `GenDiskBuilder` is using a dynamic lock class key without registering the key. This is an incorrect use of the API, which causes a `WARN` trace. Fix the issue by using a static lock class key, which is more appropriate for the situation anyway.

rust: block: do not use removed queue flag API

2024-06-20T12:54:48Z

`blk_queue_flag_set` and `blk_queue_flag_clear` was removed in favor of a new API. This caused a build error for Rust block device abstractions. Thus, use the new feature passing API instead of the old removed API.

The Rust block layer API was using the old queue limit API, which was just removed. Use the new API instead.
