userns: Add an explicit reference to the parent user namespace
I am about to remove the struct user_namespace reference from struct user_struct. So keep an explicit track of the parent user namespace. Take advantage of this new reference and replace instances of user_ns->creator->user_ns with user_ns->parent. Acked-by: Serge Hallyn <serge.hallyn@canonical.com> Signed-off-by: Eric W.
