You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: userns_linux.go
    path of file: ./repos/octant/vendor/github.com/opencontainers/runc/libcontainer/userns
    
    the code of the file until where you have to start completion: package userns

import (
	"sync"

	"github.com/openc
    
func uidMapInUserNS(uidmap []user.IDMap) bool {
	/*
	 * We assume we are in the initial user namespace if we have a full
	 * range - 4294967295 uids starting at uid 0.
	 */
	if len(uidmap) == 1 && uidmap[0].ID == 0 && uidmap[0].ParentID == 0 && uidmap[0].Count == 4294967295 {
		return false
	}
	return true
}
