For now, the security/landlock/ files didn't changed yet, but that will 
come. All other kernel APIs (and semantic) may change over time (e.g. 
LSM API, network types…). I'm working on Linus's master branch (when it 
becomes stable enough) or the linux-rolling-stable branch (from the 
stable repository). When it will be ready for a merge, we need to base 
our work on linux-next.
