| | | | | | | | | | | When /sys/kernel/debug is mounted the list can be imense, so use the pager like the other tools.

* perf_counter tools: Add more warnings and fix/annotate themIngo Molnar2009-07-011-1/+1
| | | | | | | | | | | | | | | | | Enable -Wextra. This found a few real bugs plus a number of signed/unsigned type mismatches/uncleanlinesses. It also required a few annotations All things considered it was still worth it so lets try with this enabled for now.

* perf_counter tools: Move from Documentation/perf_counter/ to tools/perf/Ingo Molnar2009-06-061-0/+20
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.
