1//! VFS Version 2 - Modern Architecture Implementation
2//!
3//! This module implements the new VFS architecture with clear separation of concerns
4//! and improved performance characteristics. The design is inspired by modern
5//! operating systems like Linux and provides:
6//!
7//! ## Core Components
8//!
9//! - **VfsEntry**: Path hierarchy "names" and "links" (similar to Linux dentry)
10//!   - Provides caching for fast path resolution
11//!   - Manages parent-child relationships in the VFS tree
12//!   - Thread-safe with weak reference cleanup
13//!
14//! - **VfsNode**: File "entity" interface (similar to Linux inode/BSD vnode)
15//!   - Abstract representation of files, directories, and special files
16//!   - Provides metadata access and type information
17//!   - Enables clean downcasting for filesystem-specific operations
18//!
19//! - **FileSystemOperations**: Driver API for filesystem implementations
20//!   - Consolidated interface for all filesystem operations
21//!   - Clean separation between VFS and filesystem drivers
22//!   - Supports modern filesystems with complex features
23//!
24//! ## Key Benefits
25//!
26//! - **Better Scalability**: Improved caching and lookup performance
27//! - **Enhanced Extensibility**: Clean interfaces for new filesystem types
28//! - **Standard OS Compatibility**: Familiar patterns for kernel developers
29//! - **Improved Symbolic Link Resolution**: Proper handling of symlink traversal
30//! - **Complex Filesystem Support**: Better support for advanced features like overlays
31//!
32//! ## Migration from VFS v1
33//!
34//! VFS v2 provides backward compatibility while offering improved APIs.
35//! New code should use the v2 interfaces for better performance and maintainability.
