Just reminding, before I tried other kernel samples (actually for eBPF
samples), I firstly installed headers:

  # make headers_install  # creates "usr/include" directory in the build top directory
  # make samples/xxx

I didn't verify Mike's patch set, just in case Mathieu encountered the
same issue and should install header ahead, so share the notes.
