[PATCH 3/4] rt-tests: cyclictest avoid unneeded warning

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



Avoid annoying warning message when tracing is not requested and the debug
file system is not available. 

The same test already protects against calling event_enable_all().
