Inquiry about chapter 8 in LFD103

imenjazirii

Hello, I am following the LFD103 course and I got stuck in chapter 8: Making Changes to a Driver section.
I followed all the steps mentioned , and now my kernel is working on linux-6.15.7 but in this section it seems that I need to use linux_mainline which is in my case a linux-6.16.0 rc6 which is an incompatible version with the one i'm using now that I just set in linux_stable.
Which version should I use ? Should I build the version 6.16.0 and reboot my system in that version or import the linux-6.15.7 version in linux_mainline and build and configure the driver there?
Thank you.

@imenjazirii I don't think it is a requirement to use mainline kernel for completing Chapter 8. If it takes time to compile the kernel, you can use the already compiled one (stable) and make changes to some driver in the stable's source and reload it to observe the message in dmesg output.
