From a5580c7f7a6d078696458d283df5d6547ad1c740 Mon Sep 17 00:00:00 2001 From: Joe Stringer Date: Thu, 8 Dec 2016 18:46:16 -0800 Subject: tools lib bpf: Add flags to bpf_create_map() Commit 6c905981743 ("bpf: pre-allocate hash map elements") introduces map_flags to bpf_attr for BPF_MAP_CREATE command. Expose this new parameter in libbpf. By exposing it, users can access flags such as whether or not to preallocate the map.
