Hi Rusty,

That RFC patch was superseded by a newer version, posted in a separate thread.
There were documentation and other printout sites to update. I posted the
non-RFC version of the patch here:

https://lkml.org/lkml/2014/2/14/4

(you should have it in your inbox)

Please let me know if I need to repost it.

Thanks!

Mathieu
