Sadly, this patch breaks the "bpf_fentry_test?" pattern in
kprobe_multi.c and kprobe_multi_test.c.

I'm considering changing the "bpf_fentry_test?" to
"bpf_fentry_test*" to solve this problem.

Another option, we can remove kretprobe_test7_result
and kretprobe_test8_result and only check
bpf_fentry_test1~6 in kprobe_multi_check.

Or......maybe I shouldn't rename them?
