[Lkw] Final rollup of all materials

[Christoph Hellwig]

Hello,

thank you so much for attending, and thank you so much for the mate
and the noticebook!

I've uploaded all materials in a tarball here:

   http://verein.lst.de/~hch/jrsl-lkw-2023.tgz

This includes all the markdown files with the instructions, the
script to run the VM, the sample patches for all steps, and the
final version of the nvme-cmb.c file.  It incorporates all the
fixes made during the workshop.

I hope you enjoyed the workshop as much as I did.
