From 5f9380572b4bb24f60cd492b17331db6ee34a516 Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Thu, 10 May 2018 10:24:39 -0700 Subject: samples: bpf: compile and link against full libbpf samples/bpf currently cherry-picks object files from tools/lib/bpf to link against. Just compile the full library and link statically against it.
