From 4f21bfed691c96da1fc85b76c16e8f6d8fe98a3d Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Mon, 12 Aug 2024 09:57:20 -0300 Subject: [PATCH] perf tests pmu: Initialize all fields of test_pmu variable Instead of explicitely initializing just the .name and .alias_name, use struct member named initialization of just the non-null -name field, the compiler will initialize all the other non-explicitely initialized fields to NULL. This makes the code more robust, avoiding the error recently fixed when the .alias_name was used and contained a random value.
