…d listing Introduce the `DynamicLookup` trait to support dynamic directory lookup and listing in the kernel filesystem (kernfs). The trait provides: - `dynamic_find`: Looks up a dynamic entry by name, returning an `IndexNode` or `None` if not found. - `dynamic_list`: Lists all dynamic entries as a vector of strings. - `is_valid_entry`: Checks if a given entry name is valid without creating it. - `create_temporary_entry`: Optional method for creating temporary entries (defaults to `None`). The trait is `Send`, `Sync`, and `Debug` to ensure thread-safety and debuggability, enabling flexible dynamic filesystem operations while maintaining compatibility with static lookups.
Add current_id method to IdAllocator struct to get the current ID pointer position, mainly for debugging purposes. This method returns the value of the current_id field of IdAllocator, which is convenient for viewing the current allocated ID position during debugging.

这个trait没见到哪里使用到了，这个目的是什么？能否把用到的地方也pr了 |
这个trait用在PID目录、cgroup目录的动态查阅，涉及部分有些多，后续会逐步pr |
