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.

Yonghong Song (3):
  bpf: use the same condition in perf event set/free bpf handler
  bpf: permit multiple bpf attachments for a single perf event
  bpf: add a test case to test single tp multiple bpf attachment
