What is your goal for the p9auth code?  Currently it is deleted in
linux-next due to a lack of development.  I see you have some cleanup
patches, but I can't apply them unless you get the non-staging patches
accepted.

If I bring the driver back from deletion, will you work to fix it up and
get it merged into mainline?

What's the word on the non-staging patches in this series being
accepted?

thanks,
