[v2] bpf: btf: include linux/types.h for u32

[PATCH bpf-next v2] bpf: btf: include linux/types.h for u32

Posted by Dmitrii Bundin 1 year, 10 months ago

Inclusion of the header linux/btf_ids.h relies on indirect inclusion of
the header linux/types.h. Including it directly on the top level helps
to avoid potential problems if linux/types.h hasn't been included
before.
