Great work with that misc device driver. Isn't that a nice and simple
way to write a character driver?
Just when you think this challenge is all about writing kernel code,
this task is a throwback to your second one. Yes, that's right,
building kernels. Turns out that's what most developers end up doing,
tons and tons of rebuilds, not writing new code. Sad, but it is a good
skill to know.
The tasks this round are:
- Download the linux-next kernel for today. Or tomorrow, just use
the latest one. It changes every day so there is no specific one

and booted it.
What is the linux-next kernel? Ah, that's part of the challenge.
For a hint, you should read the excellent documentation about how the
Linux kernel is developed in Documentation/development-process/ in the
kernel source itself. It's a great read, and should tell you all you
never wanted to know about what Linux kernel developers do and how they
