[PATCH v2 bpf-next 3/5] libbpf: add btf__new_split() API that was declared but not implemented

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Seems like original commit adding split BTF support intended to add
btf__new_split() API, and even declared it in libbpf.map, but never
added (trivial) implementation. Fix this.

Fixes: ba451366bf44 ("libbpf: Implement basic split BTF support")
