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:
. fix a potential deadlock issue discovered by Daniel.
. fix some coding style issues.Series applied.
