From fe0ce8a9d85a48642880c9b78944cb0d23e779c5 Mon Sep 17 00:00:00 2001 From: Ian Rogers Date: Fri, 28 Feb 2025 14:22:59 -0800 Subject: [PATCH] perf evlist: Add success path to evlist__create_syswide_maps Over various refactorings evlist__create_syswide_maps has been made to only ever return with -ENOMEM. Fix this so that when perf_evlist__set_maps is successfully called, 0 is returned.
