Subject: Re: [PATCH v2 00/10] userns: sysctl limits for namespaces

I won't have any more time for this until I return from vacation at the
end of the month but after a little bit of thought I think I have fixed
all of the bugs (except arguably the return value).

I have further tweaked these and made the limits per user.  Because it
occured to me that if the limits are global it is possible for one
misbehaving user to DOS another which is undesirable in princible.

I have put my updated code at:
git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace.git for-testing
