From 366d259ff597e81d90639ae21269b3f82cd4ebb7 Mon Sep 17 00:00:00 2001 From: Alexandre Ghiti Date: Wed, 2 Aug 2023 10:03:19 +0200 Subject: perf: Fix wrong comment about default event_idx Since commit c719f56092ad ("perf: Fix and clean up initialization of pmu::event_idx"), event_idx default implementation has returned 0, not idx + 1, so fix the comment that can be misleading.
