Subject: [PATCH 2/9] perf report: Ignore SIGPIPE for srcline
Date: Thu, 15 Dec 2022 11:28:10 -0800 [thread overview]
Message-ID: <20221215192817.2734573-3-namhyung@kernel.org> (raw)
In-Reply-To: <20221215192817.2734573-1-namhyung@kernel.org>
It can get SIGPIPE when it uses an external addr2line process and the
process was terminated unexpectedly. Let's ignore the signal and move
on to the next sample. The sample will get the default srcline value
anyway.
