Currently, the kprobe BPF program attachment method for bpf_load is pretty outdated. The implementation of bpf_load "directly" controls and manages(create, delete) the kprobe events of DEBUGFS. On the other hand, using using the libbpf automatically manages the kprobe event. (under bpf_link interface) This patchset refactors kprobe tracing programs with using libbpf API for loading bpf program instead of previous bpf_load implementation. Daniel T.
