Subject: [PATCH 04/10] perf tools: Do not use __perf_session__process_events() directly
Date: Thu, 29 Jan 2015 17:23:39 -0300	[thread overview]
Message-ID: <1422563025-28402-5-git-send-email-acme@kernel.org> (raw)
In-Reply-To: <1422563025-28402-1-git-send-email-acme@kernel.org>

From: Namhyung Kim <namhyung@kernel.org>

It's only used for perf record to process build-id because its file size
it's not fixed at this time due to remaining header features.

However data offset and size is available so that we can use the
perf_session__process_events() once we set the file size as the current
offset like for now.
