Linux Kernel Development - Part 1: Hello Kernel!
Skip userland and run code inside the kernel with a tiny "Hello Kernel" module that prints messages on load and unload. This introduction walks through required headers, the init and exit hooks, MODULE_* metadata, a kernel-friendly Makefile, and the basic workflow to build, insmod, rmmod and inspect messages with dmesg. It’s a hands-on first step into Linux kernel module development.
