Subject: [PATCH 02/25] perf tools: Use perf_cpu_map__nr instead of cpu_map__nr
Date: Thu, 22 Aug 2019 18:00:37 -0300 [thread overview]
Message-ID: <20190822210100.3461-3-acme@kernel.org> (raw)
In-Reply-To: <20190822210100.3461-1-acme@kernel.org>
From: Jiri Olsa <jolsa@kernel.org>
Switch the rest of the perf code to use libperf's perf_cpu_map__nr(),
which is the same as current cpu_map__nr() and remove the cpu_map__nr()
function.
