Subject: [PATCH 12/19] perf test vmlinux: Clarify which -v lines are errors or warning
Date: Thu, 1 Sep 2016 13:45:38 -0300 [thread overview]
Message-ID: <1472748345-23417-13-git-send-email-acme@kernel.org> (raw)
In-Reply-To: <1472748345-23417-1-git-send-email-acme@kernel.org>
From: Arnaldo Carvalho de Melo <acme@redhat.com>
When the 'perf test -v vmlinux' test fails, it is not clear which of the
lines are errors or warnings, clarify that adding ERR/WARN prefixes:
# perf test -F -v 1
1: vmlinux symtab matches kallsyms :
--- start ---
Looking at the vmlinux_path (8 entries long)
Using /lib/modules/4.8.0-rc4+/build/vmlinux for symbols
