How to contribute to the linux kernel

[Qianqiang Liu]


Hi all,

I am an embedded software engineer. I use Linux every day, and I appreciate its neatness and simplicity.

One day, I watched a video from Greg: https://youtu.be/LLBrBBImJt4, and I started wondering if maybe I could contribute to the Linux kernel. So, I sent a very simple (and maybe stupid) patch to the community:

It turns out that the patch was rejected.

So, my question is: how can I start contributing to the Linux kernel? Maybe I could start by fixing some small bugs?

Thanks,
