From 7678d9b3487ee3ffa550178fd1c22d8e843a876e Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Fri, 21 Jun 2024 10:05:25 -0700 Subject: [PATCH] perf report: Fix condition in sort__sym_cmp() [ Upstream commit cb39d05e67dc24985ff9f5150e71040fa4d60ab8 ] It's expected that both hist entries are in the same hists when comparing two. But the current code in the function checks one without dso sort key and other with the key. This would make the condition true in any case. I guess the intention of the original commit was to add '!' for the right side too. But as it should be the same, let's just remove it.
