Dear Eric,
I have a similar question about init_user_ns to Dave. As far as
I can tell, using init_user_ns here means we'll never get translations
based on the current process namespace. It just so happens that
include/linux/user_namespace.h doesn't allow new namespaces yet, but I
can't see why we would propagate that knowledge elsewhere.
Is there some magic about when init_user_ns should be used
regardless?
