There's no need for it anymore cilium/ebpf loader, it's not used. Signed-off-by: Jiri Olsa <[email protected]>
With the new cilium/ebpf loader there's on need to keep it there, it's not used. Signed-off-by: Jiri Olsa <[email protected]>
Switching from current bpf.BTF to cilium/epbf btf.Spec package,
which affects following places:
- the pkg/btf/btf.go package is used to cache *btf.Spec object
and red it from proper btf path (observerFindBTF)
- ValidateKprobeSpec now takes *btf.Spec object and compares spec
against it using cilium/ebpf btf interface
- Removing FreeCachedBTF because btf.Spec does not have removal function,
it will go down with the app
