I’m debugging something that is causing a lockup, where I only get a single line out on the crash (no stackdump, nada!). Frustrated, I thought about slapping printk()’s all over the place, and then thought to myself. Hmm, it would be much nicer to just hook function tracing to printk….

Coming soon: ftrace_printk!
