Hmm.... I see that the netdev folks have started an alternative to
systemtap when it comes to in-kernel debugging. I assume you have seen
the file net/ipv4/tcp_probe.c?
They use jprobes to just patch in a 'debugging module' that contains the
printk()s that might be of interest. How about this as an alternative?
