Subject: [PATCH 1/9] perf top: Do not convert address for perf_top__record_precise_ip()
Date: Fri, 11 Dec 2015 11:22:24 -0300 [thread overview]
Message-ID: <1449843752-28395-2-git-send-email-acme@kernel.org> (raw)
In-Reply-To: <1449843752-28395-1-git-send-email-acme@kernel.org>
From: Namhyung Kim <namhyung@kernel.org>
We call map->unmap_ip() before the function and call map->map_ip()
inside the function. This is meaningless and look strange since only
one of the two checks 'map'. Let's use al->addr directly.
