Inside Linux inotify: How the Kernel Tracks File Changes

This article dissects Linux’s inotify mechanism, detailing the kernel data structures, system‑call flow, and functions that generate and deliver file‑system event notifications, complete with code walkthroughs and diagrams. It explains how read/write operations trigger event creation, how events are queued in inotify_device, and how user‑space processes retrieve them via read and poll interfaces.
