Subject: [PATCH v2 28/48] libperf: Use cpu not index for evsel mmap
Date: Wed, 22 Dec 2021 23:45:21 -0800 [thread overview]
Message-ID: <20211223074541.3318938-29-irogers@google.com> (raw)
In-Reply-To: <20211223074541.3318938-1-irogers@google.com>
Fix issue where evsel's CPU map index was being used as the mmap cpu.
