Just clarify one thing, I defined the kfunc in new patch: int bpf_perf_event_aux_pause(void *p__map, u64 flags, u32 pause) Unlike your suggestion, I defined the first parameter as "void *p__map" (I refers to bpf_arena_alloc_pages()) rather than "struct bpf_map *map". This is because the BPF program will pass a variable from the map section, rather than passing a map pointer.
This is correct,
see commit 8d94f1357c00 ("bpf: Recognize '__map' suffix in kfunc arguments")
