Actually given that kernel hooks has been around for a very long time, and
since static probe points are required anyway, I'm thinking of actually
reusing as much from kernel hooks as possible to implement the dynamic
instrumentation component of the kernel markers.

Now if only I could find the pages where IBM now hosts its projects ...
there are a lot of broken pointers when trying to access stuff like
kernel hooks, dprobes, kprobes, etc. Google, at least, can't find
anything meaningfull.
