ext2 Filesystem Implementation

This module implements an ext2 filesystem driver for the VFS v2 architecture. It provides support for reading and writing ext2 filesystems on block devices, particularly designed to work with virtio-blk devices.

§Features

  • Full ext2 filesystem support
  • Read and write operations
  • Directory navigation
  • File creation, deletion, and modification
  • Integration with VFS v2 architecture
  • Block device compatibility

§Architecture

The ext2 implementation consists of:

  • Ext2FileSystem: Main filesystem implementation
  • Ext2Node: VFS node implementation for files and directories
  • Ext2Driver: Filesystem driver for registration
  • Data structures for ext2 format (superblock, inode, directory entries, etc.)
