Subject: [PATCH 35/38] perf tools: Fix progress ui to support multi thread
Date: Tue,  3 Mar 2015 12:07:47 +0900	[thread overview]
Message-ID: <1425352070-1115-36-git-send-email-namhyung@kernel.org> (raw)
In-Reply-To: <1425352070-1115-1-git-send-email-namhyung@kernel.org>

Split ui_progress struct into global and local one.  Each thread
updates local struct without lock and only updates global one if
meaningful progress is done (with lock).

To do that, pass struct ui_progress to __perf_session__process_event()
and set it for the total size of multi-file storage.
