We need to get all the kernel function that can be traced sometimes, so we move the get_syms() and get_addrs() in kprobe_multi_test.c to trace_helpers.c and rename it to bpf_get_ksyms() and bpf_get_addrs(). Signed-off-by: Menglong Dong <dongml2@chinatelecom.cn>
Some functions is recursive for the kprobe_multi and impact the benchmark results. So just skip them. Signed-off-by: Menglong Dong <dongml2@chinatelecom.cn>
For now, the benchmark for kprobe-multi is single, which means there is only 1 function is hooked during testing. Add the testing "kprobe-multi-all", which will hook all the kernel functions during the benchmark. And the "kretprobe-multi-all" is added too. Signed-off-by: Menglong Dong <dongml2@chinatelecom.cn>
