Subject: [PATCH bpf-next 8/9] libbpf: introduce bpf_map_lookup_elem_flags()

From: Alexei Starovoitov <[email-masked]>
Date: Tue, 15 Jan 2019 21:08:29 -0800

Introduce
int bpf_map_lookup_elem_flags(int fd, const void *key, void *value, __u64 flags)
helper to lookup array/hash/cgroup_local_storage elements with BPF_F_LOCK flag.
