ReadFileNoStat uses ioutil.ReadAll to read contents of entire file. This is similar to ioutil.ReadFile but without the call to os.Stat, because many files in /proc and /sys report incorrect file sizes (either 0 or 4096). Reads a max file size of 512kB. For files larger than this, a scanner should be used.
func ( string) ([]byte, error) {
	const  = 1024 * 512

	,  := os.Open()
	if  != nil {
		return nil, 
	}
	defer .Close()

	 := io.LimitReader(, )
	return ioutil.ReadAll()
