[PATCH bpf-next 0/2] bpf: Fix kprobe_multi return probe backtrace

[Jiri Olsa]

hi,
Andrii reported that backtraces from kprobe_multi program attached
as return probes are not complete and showing just initial entry [1].

Sending the fix together with bpf_get_func_ip inline revert, which is
no longer suitable.

thanks,
jirka
