Merge branch 'cleanup the legacy probe_event on failed scenario'
Chuang Wang says:
====================
A potential scenario, when an error is returned after
add_uprobe_event_legacy() in perf_event_uprobe_open_legacy(), or
bpf_program__attach_perf_event_opts() in
bpf_program__attach_uprobe_opts() returns an error, the uprobe_event
that was previously created is not cleaned.
At the same time, the legacy kprobe_event also have similar problems.
With these patches, whenever an error is returned, it ensures that
the created kprobe_event/uprobe_event is cleaned.
V1 -> v3:
- add detail commits
- call remove_kprobe_event_legacy() on failed bpf_program__attach_perf_event_opts()
v3 -> v4:
- cleanup the legacy kprobe_event on failed add/attach_event
====================
