Subject: [PATCH 19/46] perf sort: Introduce addr_map_symbol__srcline() to make code more compact
Date:   Tue,  5 Jun 2018 14:50:03 -0300
Message-Id: <20180605175030.32549-20-acme@kernel.org>
In-Reply-To: <20180605175030.32549-1-acme@kernel.org>

Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

From: Arnaldo Carvalho de Melo <acme@redhat.com>

Since we have 'struct addr_map_symbol' and the srcline sort order keys
all operate on those, make the code more compact by introducing a
function that receives a pointer to such struct and expands the
arguments to map__srcline().
