Subject: [PATCH 39/40] perf data: Implement 'index' subcommand
Date: Mon, 18 May 2015 09:30:54 +0900	[thread overview]
Message-ID: <1431909055-21442-40-git-send-email-namhyung@kernel.org> (raw)
In-Reply-To: <1431909055-21442-1-git-send-email-namhyung@kernel.org>

The index command first splits a given data file into intermediate
data files and merges them into a final data file with an index table
so that it can processed using multi threads.  The HEADER_DATA_INDEX
feature bit is added to distinguish data file that has an index table.
