@Alexei and @Daniel,

there is a trivial conflict with bpf_loop helper (because the series was not
merged when I posted v19):

commit e6f2dd0f80674e9d5960337b3e9c2a242441b326
Author: Joanne Koong <joannekoong@xxxxxx>

    bpf: Add bpf_loop helper

Do you want me to post v20 after waiting for some more feedbacks on v19?

Regards,
Lorenzo
