Numerous refactoring that rewrites BPF programs written with bpf_load to use the libbpf loader was finally completed, resulting in BPF programs using bpf_load within the kernel being completely no longer present. This patchset refactors remaining bpf programs with libbpf and completely removes bpf_load, an outdated bpf loader that is difficult to keep up with the latest kernel BPF and causes confusion. Changes in v2: - drop 'move tracing helpers to trace_helper' patch - add link pinning to prevent cleaning up on process exit - add static at global variable and remove unused variable - change to destroy link even after link__pin() - fix return error code on exit - merge commit with changing Makefile Daniel T.
