In the derived_probe_group registration logic, each registration
attempt only passes an rc and the probe_point string back for
reporting. It would be nice to have an additional char[] available
to print more stuff into, so for example if a kprobe_register fails,
we don't just get
WARNING: probe
module("kvm").function("kvm_vcpu_init@arch/x86/kvm/../../../virt/kvm/kvm_main.c:6\
17").call
registration error (rc -22)
but also something else, which for kprobes could include data regarding the
calculation of the kprobe address.
