Hi, I have a segfault when inserting dccp_probe module on Dave Miller's tree *without* Ian's patches. I got it using this cmd line :
Question, does it also segfaults _with_ Ian's patches?

I ask this because it is segfaulting at dccpprobe_init time, when it is registering the jprobe. To me it looks like something changed in the jprobes infrastructure and we are seeing a fallout from that. But I haven't investigated this more than looking at this backtrace.
