We have a build failure in 5.15.153: libbpf.c:74:12: error: 'map_set_def_max_entries' used but never defined [-Werror] 74 | static int map_set_def_max_entries(struct bpf_map *map); | ^~~~~~~~~~~~~~~~~~~~~~~ cc1: all warnings being treated as errors
this function is not defined in 5.15.153
$ git grep "map_set_def_max_entries" tools/lib/bpf/libbpf.c:static int map_set_def_max_entries(struct bpf_map *map); tools/lib/bpf/libbpf.c: err = map_set_def_max_entries(map->inner_map);
This is introduced by PATCH: "[PATCH 5.15 067/317] libbpf: Apply map_set_def_max_entries() for inner_maps on creation" in this series
This missing function is defined in commit: a4fbfdd7a160 ("libbpf: Fix BPF_MAP_TYPE_PERF_EVENT_ARRAY auto-pinning") and pulling this in needs some conflict resolution.
So I think for now the best idea is to drop this patch[067/317]
Thanks, Harshit
