Subject: [PATCH V6 22/25] perf tools: Hit all build ids when AUX area tracing
Date: Mon, 16 Mar 2015 14:41:44 +0200	[thread overview]
Message-ID: <1426509707-24961-23-git-send-email-adrian.hunter@intel.com> (raw)
In-Reply-To: <1426509707-24961-1-git-send-email-adrian.hunter@intel.com>

We need to include all buildids when a perf.data
file contains AUX area tracing data because we
do not decode the trace for that purpose because
it would take too long.
