Subject: [PATCH bpf-next v2 0/3] selftests/bpf: benchmark all symbols for kprobe-multi

Add the benchmark testcase "kprobe-multi-all", which will hook all the
kernel functions during the testing.

This series is separated out from [1].

Changes since V1:
* introduce trace_blacklist instead of copy-pasting strcmp in the 2nd
  patch
* use fprintf() instead of printf() in 3rd patch
