From d205a3a665158f4229845aaa29245b19a9e4be03 Mon Sep 17 00:00:00 2001 From: Adrian Hunter Date: Fri, 6 May 2022 15:25:43 +0300 Subject: [PATCH] perf auxtrace: Do not mix up mmap idx The idx is with respect to evlist not evsel. That hasn't mattered because they are the same at present. Prepare for that not being the case, which it won't be when sideband tracking events are allowed on all CPUs even when auxtrace is limited to selected CPUs.
