Re: [PATCH 2/5] net/sunrpc: use kstrtoul, etc

In looking through some examples, I see, e.g.:

 	if (strict_strtoul(buf, 10, &val) < 0)
  		return -EINVAL;
 	if (val < 1 || val > 2)
  		return -EINVAL;

In this case the only valid values are 1 and 2, which are much smaller 
than the u8 range.  Is it useful to use kstrtou8 anyway?  I see that 
kstrtou8 returns -ERANGE not -EINVAL when the value is out of bounds.  If 
kstrtou8 is to be used, should the subsequent if (val < 1 || val > 2) now 
return -ERANGE to be consistent?
