Hmm. That second one looks like it really should have just used
"kmemdup()" (and a zero termination) instead, since it has already
done all the string length calculations.

Oh well. I guess the strndup() works too, but it seems kind of odd to
do a strnlen() there when you have literally limited 'len' to smaller
than the string you are going to duplicate.
