From 864709302a80f26fa9da3be5b47304f0b8bae192 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Sat, 6 Jun 2009 20:33:43 +0200 Subject: perf_counter tools: Move from Documentation/perf_counter/ to tools/perf/ Several people have suggested that 'perf' has become a full-fledged tool that should be moved out of Documentation/. Move it to the (new) tools/ directory.
