[PATCH] Add try_to_freeze() to rt-test kthreads
When CONFIG_RT_MUTEX_TESTER is enabled kernel refuses to suspend the machine because it's unable to freeze the rt-test-* threads. Add try_to_freeze() after schedule() so that the threads will be freezed correctly; I've tested the patch and it lets the notebook suspends and resumes nicely.
