From 6e68e6c5e4b67a02aaa406da6124ea5cae7d5e10 Mon Sep 17 00:00:00 2001 From: Masami Hiramatsu Date: Mon, 22 Sep 2014 23:42:50 +0000 Subject: ftracetest: Initial commit for ftracetest ftracetest is a collection of testcase shell-scripts for ftrace. To avoid regressions of ftrace, these testcases check correct ftrace behaviors. If someone would like to add any features on ftrace, the patch series should have at least one testcase for checking the new behavior.
