From 292e1d73b125d7a3fd7ff382557e003ece3c0d65 Mon Sep 17 00:00:00 2001 From: Andrii Nakryiko Date: Sun, 12 Jan 2020 23:31:39 -0800 Subject: [PATCH] libbpf: Clean up bpf_helper_defs.h generation output bpf_helpers_doc.py script, used to generate bpf_helper_defs.h, unconditionally emits one informational message to stderr. Remove it and preserve stderr to contain only relevant errors. Also make sure script invocations command is muted by default in libbpf's Makefile.
