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: net_conntrackstat.go
    path of file: ./repos/buildkit/vendor/github.com/prometheus/procfs
    
    the code of the file until where you have to start completion: // Copyright 2020 The Prometheus Authors
// Licensed under the Apach
    
func readConntrackStat(path string) ([]ConntrackStatEntry, error) {
	// This file is small and can be read with one syscall.
	b, err := util.ReadFileNoStat(path)
	if err != nil {
		// Do not wrap this error so the caller can detect os.IsNotExist and
		// similar conditions.
		return nil, err
	}

	stat, err := parseConntrackStat(bytes.NewReader(b))
	if err != nil {
		return nil, fmt.Errorf("%s: Cannot read file: %v: %w", ErrFileRead, path, err)
	}

	return stat, nil
}
