Sorry, what do you mean by 'the non-staging patches'?  Do you mean
the staging patches that were dropped, the cleanup patches (that
wouldn't make sense), or another set of patches?

Again, I'm not quite sure which you mean by the non-staging patches,
or what you mean by accepted - do you mean general community acceptance
of the base p9auth patches, or acceptance of my p9uath patches by
Ashwin etc?
