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?
