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,
