From bc1bafbbe9b3558d7789ff151ef4f185b6ad21f3 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Mon, 1 May 2017 12:43:49 -0700 Subject: bpf: Move endianness BPF helpers out of bpf_util.h We do not want to include things like stdio.h and friends into eBPF program builds. bpf_util.h is for host compiled programs, so eBPF C-code helpers don't really belong there. Add a new bpf_endian.h as a quick fix for this for now. Signed-off-by: David S.
