函数名称：perf_event_bpf_emit_ksymbols

函数原型：static void perf_event_bpf_emit_ksymbols(struct bpf_prog *prog, enum perf_bpf_event_type type)

返回类型：void

参数：

类型参数名称
struct bpf_prog *prog
enum perf_bpf_event_typetype
8257  unregister等于type恒等于PERF_BPF_EVENT_PROG_UNLOAD
8261  如果 used by non-func prog as the number of func progs 恒等于0则
8262  bpf_get_prog_name(prog, sym)
8263  perf_event_ksymbol(PERF_RECORD_KSYMBOL_TYPE_BPF, (u64)(unsignedlong)bpf_func, Size of jited insns in bytes , unregister, sym)
8266  否则
8267  以i小于 used by non-func prog as the number of func progs 循环
8268  subprog等于func[i]
8270  bpf_get_prog_name(subprog, sym)
8271  perf_event_ksymbol(PERF_RECORD_KSYMBOL_TYPE_BPF, (u64)(unsignedlong)bpf_func, Size of jited insns in bytes , unregister, sym)
