Hi Jonathan,
There is this Linux Plumbers video: https://www.youtube.com/watch?v=KXuZi9aeGTw And the pdf: http://pdxplumbers.osuosl.org/2013/ocw//system/presentations/1653/original/LPC%20-%20User%20Threading.pdf
I did not reference them in the patchset because links to sites other than kernel.org are strongly discouraged... I will definitely add a documentation patch.
Feel free to reach out to me directly or through this LKML thread if you have any questions.
Do you think a documentation patch would be useful at this point, as opposed to a free-form email discussion?
Thanks, Peter
