This project keeps the Linux Kernel Module Programming Guide reasonably up to date, with working examples for recent 5.x kernel versions. The guide has been around since 2001 and most copies of it on the web only describe old 2.6.x kernels.

The original guide may be found at http://www.tldp.org/LDP/lkmpg/
