Date: Mon, 11 May 2020 13:32:34 +0200 From: Matteo Croce <mcroce@...hat.com> To: bpf@...r.kernel.org, netdev@...r.kernel.org Cc: linux-kernel@...r.kernel.org, Alexei Starovoitov <ast@...nel.org>, Joe Stringer <joe@....org>, Jakub Kicinski <kuba@...nel.org> Subject: [PATCH bpf] samples: bpf: fix build error GCC 10 is very strict about symbol clash, and lwt_len_hist_user contains a symbol which clashes with libbpf: /usr/bin/ld: samples/bpf/lwt_len_hist_user.o:(.bss+0x0): multiple definition of `bpf_log_buf'; samples/bpf/bpf_load.o:(.bss+0x8c0): first defined here collect2: error: ld returned 1 exit status bpf_log_buf here seems to be a leftover, so removing it.
