I don't know the discipline you keep for the compat backports. However I expect you can simplify this bit considerably by removing the USER_NS case as it will never be true, except in 3.5 where this code already in exists. You can further simplify things by leaving out the overflowuid and overflowgid cases from from_kuid_munged, as for a backport I doubt anyon will care if the value is -1 or overflowuid.
