Subject: [PATCH bpf-next] libbpf: fix usage of u32 in userspace code
Date: Mon, 25 Nov 2019 13:29:48 -0800 [thread overview]
Message-ID: <20191125212948.1163343-1-andriin@fb.com> (raw)
u32 is not defined for libbpf when compiled outside of kernel sources (e.g.,
in Github projection). Use __u32 instead.
Fixes: b8c54ea455dc ("libbpf: Add support to attach to fentry/fexit tracing progs")
