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: knobs_linux_test.go
    path of file: ./repos/docker-ce/components/engine/libnetwork/osl/kernel
    
    the code of the file until where you have to start completion: package kernel

import (
	"testing"

	"github.com/sirupsen/logrus"
	"gotest.tools/v3/assert"
	is "gotest.tools/v3/assert/cmp"
)

func TestReadWriteKnobs(t *testing.T) {
	for _, k := range []string{
		"net.ipv4.neigh.default.gc_thresh1",
		"net.ipv4.neigh.default.gc_thresh2",
		"net.ipv4.neigh.default.gc_thresh3",
	} {
		// Check if the test is able to read the value
		v, err := readSystemProperty(k)
		if err != nil {
			logrus.WithError(err).Warnf("Path %v not readable", k)
			// the path is not there, skip this
    
func TestReadWriteKnobs(t *testing.T) {

	} {

		v, err := readSystemProperty(k)
		if err != nil {
