Wed May 11 13:36:23 CEST 2016
From: Li Wang <liwang@redhat.com>
This commit is just preparing for the upcoming patch set.
So do rename work, not changing anything of the content.
Changs:
- renamed: ftrace_stress_test/ --> ftrace_test/
- extracted: ftrace_stress_test.sh --> ftrace_lib.sh
- modified: ftrace_stress_test.sh
