Subject: [PATCH v2 8/9] perf srcline: Add missed addr2line closes
Date: Wed, 31 Jan 2024 16:15:02 -0800 [thread overview]
Message-ID: <20240201001504.1348511-8-irogers@google.com> (raw)
In-Reply-To: <20240201001504.1348511-1-irogers@google.com>
The child_process for addr2line sets in and out to -1 so that pipes
get created. It is the caller's responsibility to close the pipes,
finish_command doesn't do it. Add the missed closes.
Fixes: b3801e791231 ("perf srcline: Simplify addr2line subprocess")
