From 906049c8276eb99af997f73d602649a98e360035 Mon Sep 17 00:00:00 2001 From: Adrian Hunter Date: Tue, 3 Dec 2013 09:23:10 +0200 Subject: perf tools: Do not disable source line lookup just because of 1 failure Looking up an ip's source file name and line number does not succeed always. Current logic disables the lookup for a dso entirely on any failure. Change it so that disabling never happens if there has ever been a successful lookup for that dso but disable if the first 123 lookups fail.
