The first major piece of this,which forms the core infrastructure for Dynamic Probes, now reworked in the form of a simpler minimalist patch for 2.5, based on suggestions and review comments from Rusty is already available.
It was sent to Linus by Rusty this Saturday, posted to lkml, under the title "Kernel Probes for i386 2.5.26", and sort of distills the essence of the dprobes mechanism into a self-sufficient and more generic patch.
The patch contains the probing mechanism for kernel space probe points (it takes care of all the low level details of breakpoint + single step, including handling several subtle issues, tricky conditions and races) and provides an in-kernel interface that can be used by modules to register a probepoint(breakpoint) and a handler routine to be invoked when the probe is hit.
We are now working on follow on patches to extend the generic infrastructure with fine-grained serialization, data watchpoint probes and user space probing support, as we have in the full-blown Dynamic Probes implementation.
