From ef6ae724253429ac70d81e65d052f6a346d330bd Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Fri, 20 Nov 2009 20:51:29 -0200 Subject: [PATCH] perf symbols: Change the kernel DSO name if it comes from kallsyms MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit So that the user have a clearer indication about the source of the symbols, as we only state buildid mismatches in verbose mode, because 'perf top' would overwrite such warning anyway.
