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.
