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: nameWithoutNamlen.go
    path of file: ./repos/kubernetes/vendor/github.com/karrick/godirwalk
    
    the code of the file until where you have to start completion: // +build nacl linux js solaris

package godirwalk

import (
	"bytes"
	"reflect"
	"syscall"
	"unsafe"
)

// nameOffset is a compile time constant

func nameFromDirent(de *syscall.Dirent) (name []byte) {
	// Because this GOOS' syscall.Dirent does not provide a field that specifies
	// the name length, this function must first calculate the max possible name
	// length, and then search for the NULL byte.
	ml := int(de.Reclen) - nameOffset

	// Convert syscall.Dirent.Name, which is array of int8, to []byte, by
	// overwriting Cap, Len, and Data slice header fields to the max possible
	// name length computed above, and finding the terminating NULL byte.
