From a78cdee6fbb136694334ade4cedb331a9d0b4d5e Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Tue, 18 Sep 2018 05:32:10 -0700 Subject: [PATCH] perf script: Print DSO for callindent Now that we don't need to print the IP/ADDR for callindent the DSO is also not printed. It's useful for some cases, so add an own DSO printout for callindent for the case when IP/ADDR is not enabled.
