Subject: [PATCH 02/22] perf stat: Add aggr creators that are passed a cpu.
Date: Tue, 7 Dec 2021 18:45:47 -0800 [thread overview]
Message-ID: <20211208024607.1784932-3-irogers@google.com> (raw)
In-Reply-To: <20211208024607.1784932-1-irogers@google.com>
The cpu_map and index can get confused. Add variants of the cpu_map__get
routines that are passed a cpu. Make the existing cpu_map__get routines
use the new functions with a view to remove them when no longer used.
