Kaiwan N. Billimoria

Kaiwan N. Billimoria taught himself BASIC programming on his dad's IBM PC back in 1983. He was programming in C and Assembly on DOS until he discovered the joys of Unix, and by around 1997, Linux! Kaiwan has worked on many aspects of the Linux system programming stack, including Bash scripting, system programming in C, kernel internals, device drivers, and embedded Linux work. He has actively worked on several commercial/FOSS projects. His contributions include drivers to the mainline Linux OS and many smaller projects hosted on GitHub. His Linux passion feeds well into his passion for teaching these topics to engineers, which he has done for well over two decades now. He's also the author of Hands-On System Programming with Linux, Linux Kernel Programming (and its Part 2 book) and Linux Kernel Debugging. It doesn't hurt that he is a recreational ultrarunner too.

Coding style guidelines for kernel developers

Many large projects specify their own set of coding guidelines; so does the Linux kernel community. Adhering to the Linux kernel coding style guidelines is a really good idea when writing kernel and/or kernel module code. You can see the style guidelines officially documented here: https://www.kernel.org/doc/html/latest/process/coding-style.html (please do read them!).

Furthermore, as part of the (quite exhaustive) code-submission checklist(s) for developers like you wanting to upstream your code, you are expected to run your patch through a Perl script that checks your code for congruence with the Linux kernel coding style: scripts/checkpatch.pl.

By default, this script only runs on a well-formatted git patch. It’s possible to run it against standalone C code (as in your out-of-tree kernel module code), as follows (as our “better” Makefile indeed does):

<kernel-src>/scripts/checkpatch.pl --no-tree...
