Apparently it's not, though. The author here had some baseline knowledge of how Linux kernel modules work, but the impression I got is that they would not have been able to do this on their own without a lot of learning.

Now that's some gatekeeping right there. "Only experts can write kernel modules" is a pretty toxic attitude to have.

Anyone can write kernel module.

On their computers.

Not mine.
