Subject: [PATCH 27/31] perf top: Fix top.call-graph config option reading
Date: Tue, 13 Mar 2018 09:05:04 -0300	[thread overview]
Message-ID: <20180313120508.29327-28-acme@kernel.org> (raw)
In-Reply-To: <20180313120508.29327-1-acme@kernel.org>

From: Yisheng Xie <xieyisheng1@huawei.com>

When trying to add the "call-graph" variable for top into the
.perfconfig file, like:

      [top]
            call-graph = fp

I that perf_top_config() do not parse this variable.

Fix it by calling perf_default_config() when the top.call-graph variable
is set.
