Thanks, basically I'm good at this change.
Could you also rename several functions which handles trace_kprobe
instead of trace_probe? (as you did on trace_probe_XXX())
e.g.

Now this allocates trace_kprobe instead of trace_probe, so
this should be called as alloc_trace_kprobe().
Below functions should also be renamed.

For below two, comments should be updated too.
