To be honest I don't know how paranoid we want to get, we could end up
putting WARN's all over the kernel :)
In this case I guess if the size is too large we overflow the buffer on
the kernel stack, so we should at least check the size.
But does it need a WARN? I'm not sure. If we had a case that was passing
a out-of-bound size hopefully we would notice in testing? :)
You're right, a simpler check should suffice. I will send an updated
patch.
This[1] patch indeed also makes those -Wstringop-overflow warnings go away. :)
