From 86d8d29634de4464d568e7c335c0da6cba64e8ab Mon Sep 17 00:00:00 2001 From: Hitoshi Mitake Date: Sat, 30 Jan 2010 20:43:23 +0900 Subject: [PATCH] perf tools: Add __data_loc support This patch is required to test the next patch for perf lock. At 064739bc4b3d7f424b2f25547e6611bcf0132415 , support for the modifier "__data_loc" of format is added. But, when I wanted to parse format of lock_acquired (or some event else), raw_field_ptr() did not returned correct pointer. So I modified raw_field_ptr() like this patch. Then raw_field_ptr() works well.
