| |
Perf trace can augment system calls with a BPF program passed as an event. The BPF code for this lives in examples. This patch fixes the example code to not used deprecated/removed APIs in libbpf. As libbpf has similar header files to tools/perf/include/bpf the code is transitioned to use the more standard libbpf code and the perf BPF header files removed.
Ian Rogers (7): perf trace: Raw augmented syscalls fix libbpf 1.0+ compatibility perf trace: Etcsnoop fix libbpf 1.0+ compatibility perf trace: Augmented syscalls fix libbpf 1.0+ compatibility perf trace: hello fix libbpf 1.0+ compatibility perf trace: empty fix libbpf 1.0+ compatibility perf trace: 5sec fix libbpf 1.0+ compatibility perf bpf: Remove now unused BPF headers
