[PATCH v10 0/9] proc: modernize proc to support multiple private instances

[Eric W. Biederman]

Overall this patchset looks good.

I have found a couple of nits.  The biggest is the potential ABI change.
I would be surprised if someone is using the new mount ABI so changing
that may not be a regression.  But it is worth a close look.

One way or another I will ensure we get this in linux-next after the
merge window closes.
