Subject: [PATCH 5/5] perf record: Force ignore_missing_thread for uid option
Date: Mon, 12 Dec 2016 11:35:43 +0100	[thread overview]
Message-ID: <1481538943-21874-6-git-send-email-jolsa@kernel.org> (raw)
In-Reply-To: <1481538943-21874-1-git-send-email-jolsa@kernel.org>

Enable perf_evsel::ignore_missing_thread for -u option
to ignore complete failure if any of the user's processes
die between its enumeration and time we open the event.
