Test preformed =========
part of the contest package:
2) launch oprofile (if you use gui oprof_start &)
1) prepare commands export tmpfile=foobar.log
before youn run io_halfmem click on "start profiler" run io_halfmem
wait 15 seconds
op_time -l which will dump the calls and time. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
