Subject: [PATCH 11/21] perf tools: Store compression id into struct dso
Date: Mon, 20 Aug 2018 13:15:52 -0300	[thread overview]
Message-ID: <20180820161602.6830-12-acme@kernel.org> (raw)
In-Reply-To: <20180820161602.6830-1-acme@kernel.org>

From: Jiri Olsa <jolsa@kernel.org>

Add comp to 'struct dso' to hold the compression index.  It will be used
in the following patches.
