From 43cbcd8acb4c992cbd22d1ec8a08c0591be5d719 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Wed, 1 Jul 2009 12:28:37 -0300 Subject: perf_counter tools: Share rbtree.with the kernel The tools/perf/util/rbtree.c copy already drifted by three csets: 4b324126e0c6c3a5080ca3ec0981e8766ed6f1ee 4c60117811171d867d4f27f17ea07d7419d45dae 16c047add3ceaf0ab882e3e094d1ec904d02312d So remove the copy and use the lib/rbtree.c directly, sharing the source code while still generating a separate object file, since tools/perf uses a far more agressive -O6 switch.
