> This patch set adds support to permit multiple bpf prog attachments
> for a single perf tracepoint event. Patch 1 does some cleanup such
> that perf_event_{set|free}_bpf_handler is called under the
> same condition. Patch 2 has the core implementation, and
> Patch 3 adds a test case.

> Changelogs:
> v2 -> v3:
>   . fix compilation error.
> v1 -> v2:
