Allocated?

Thanks for your reply, Sergei. I used 'allocated' because kmemdup_nul()
does some allocation in its implementation. And its docs descrips:

Describes?

"Return: newly allocated copy of @s with NUL-termination or %NULL in
case of error". I think it is proper to use 'allocated' here. But it
could be 'assigned', which is better, right?

I was only trying to point out the typos in this word. :-)

Thanks
Gen

NULL when fails. So 'val' should be checked.
