Announce Linux kernel labs project

[Daniel Baluta]

Hi all,

The Linux kernel labs documentation is a collection of "labs" for
various device driver topics. For each topic there are two parts: a
walk-through which explain the basic concepts and a hands-on part which
contains a few exercises.

The kernel labs are integrated with Linux kernel Documentation
system:

We kindly appreciate your feedback, directly here or via
Issues/Pull Requests on github.

thanks,
Daniel.
