You can find the PDF of Robert Love's book "Linux Kernel Programming" on GitHub. The book is licensed under the GNU Free Documentation License.
However, the Linux kernel API changes rapidly. A textbook written three years ago will likely feature deprecated functions. This is where repositories become invaluable. They provide:

Create a file named Makefile in the exact same directory as your C source code:
Before diving into files, you must establish a structured learning path. Kernel development cannot be learned by random guessing. Follow this sequence: You can find the PDF of Robert Love's
The repository for the free guide mentioned above. It often includes updated code examples that are compatible with modern kernel versions. C. Linux Kernel Development Examples (Various Repos)
Learn to create, compile, load ( insmod ), and remove ( rmmod ) modules. Understand Kernel APIs: Study printk , kmalloc , and kfree . A textbook written three years ago will likely
If you can tell me (e.g., driver development, scheduling, or networking), I can provide more targeted, high-quality PDF guides and GitHub project examples .
LKMs let you extend the kernel's capabilities without rebooting the system. They are ideal for writing device drivers. Every module requires two basic entry points:
