bpf: add support to read sample address in bpf program This commit adds new field "addr" to bpf_perf_event_data which could be read and used by bpf programs attached to perf events. The value of the field is copied from bpf_perf_event_data_kern.addr and contains the address value recorded by specifying sample_type with PERF_SAMPLE_ADDR when calling perf_event_open.
