From f9d5d549d2c2934be84b0bc7e5e034834459f591 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Wed, 1 Apr 2015 13:29:25 -0300 Subject: [PATCH] perf scripting: No need to pass thread twice to the scripting callbacks It is already in the addr_location, so remove the redundant 'thread' parameter from the callback signatures.
