Hi, I am now working on an example to see if what I suggested earlier is possible.
During this, I encountered a problem in Kprobes on x86 that prevents placing them on the insns with %rip-relative addressing. register_kprobe() returns -EINVAL in such cases because __copy_instruction() returns 0 (arch/x86/kernel/kprobes/core.c). The latter is due to the second call to kernel_insn_init() which zeroes the struct insn instance, including insn.length. I will send a patch shortly, please consider it for inclusion.
