This article walks readers through Linux file‑system fundamentals, explains the role of the Virtual File System (VFS), dives deep into ext2 structures such as superblocks, group descriptors, block and inode bitmaps, and provides complete C code for reading file contents directly by inode number.
This article guides readers through Linux file system fundamentals, explaining the role of the virtual file system (VFS), detailed structures of the ext2 superblock, group descriptors, block and inode bitmaps, and provides C code examples for extracting and reading file data directly via inode numbers.
This article explains the design of Linux file systems, the role of inodes, data blocks, superblocks, and the Virtual File System layer that provides a unified interface for diverse storage back‑ends, detailing core structures, registration, mounting, and file operation workflows.
The article provides a detailed code-level walkthrough of F2FS’s superblock, Segment Information Table, Node Address Table, Summary Area, and Main Area structures, explaining each field, entry layout, and their roles in managing segments, inodes, and data within the filesystem.
This article explains the Linux virtual file system (VFS) architecture, its role in abstracting concrete file systems, and details core kernel structures such as superblocks, inodes, dentries, file objects, and their relationships to processes, providing code examples and diagrams for clarity.
This article explains the layered architecture of Linux file systems, how generic API calls like read operate across different storage media, demonstrates creating and mounting loop‑back file systems with dd, losetup, mke2fs and mount commands, and details the core VFS structures such as superblock, inode, dentry and buffer cache.
