Dear Clark Williams,
When we try to run ftrace with cyclictest command of rt-test testsuite,
We view the error according to base kernel version.
We need to modify this hard coded interface.
* Test environment:
. -rt patch version : 2.6.33.7.2-rt30
. rt-tests repository version : 0.72

Subject: [PATCH] [rt-tests:cyclictest] Fixed incorrect wakeup reset interface
When we try to run ftrace with cyclictest command of rt-test,
We view the error according to base kernel version.
We need to modify this hard coded interface.
