From c97b40e4d15f13a36cd037d598e45cbe9e1e5757 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Thu, 1 Sep 2016 10:56:06 -0300 Subject: [PATCH] perf symbols: Check symbol_conf.allow_aliases for kallsyms loading too We can allow aliases to be kept, but we were checking this just when loading vmlinux files, be consistent, do it for any symbol table loading code that calls symbol__fixup_duplicate() by making this function check .allow_aliases instead.
