I'm not sure if everyone noticed this on LKML last night, but here is an
example of somebody writing a kprobes based tool that an eventual
systemtap script should be able to easily handle.
If anything it shows the type of functionality normal kernel hackers are
looking for.

Hello, guys.
I've implemented a very dumb and simple kprobes wrapper which
basically just prints "HERE!" messages. It's consisted of a kernel
module and a perl script. It compiles happily as an external module
without any modification to the kernel. It only requires kprobes and
kallsyms to be compiled in.
Message printing can be filtered on several conditions (uid, pid, irq
count...), and it also supports simple %x substitutions to report
runtime variables. Please take a look at the following page for more
information.

Thanks.
