Subject: [PATCH 22/22] perf symbols: Do not open device files
Date: Tue, 20 Sep 2016 17:03:42 -0300 [thread overview]
Message-ID: <1474401822-18902-23-git-send-email-acme@kernel.org> (raw)
In-Reply-To: <1474401822-18902-1-git-send-email-acme@kernel.org>
From: Jiri Olsa <jolsa@redhat.com>
The dso__read_binary_type_filename gets the dso's file name to open. We
need to check it for regular file before trying to open it, otherwise we
might get stuck with device file.
