Argh, went to "cancel" that previous msg and retry when I realized you meant it was
with *your* patch installed, managed to send it anyhow..

I wonder if the only reason it's working for you is because gcc is doing
some tail-recursion magic on the kcalloc() call (which calls to __kmalloc),
which just happens to make it work, and if the tail-recursion wasn't happening
it would be busticated.
